Formulation of a novel anti-leukemia drug and evaluation of its therapeutic effects in comparison with Cytarabine

In the recent research, we investigated the application of gold nanoparticles green-synthesized by Alhagi maurorum aqueous extract in the treatment of several types of leukemia, i.e. acute T cell leukemia, acute lymphoblastic leukemia, and acute myeloid leukemia. Different techniques such as transmission electron microscopy (TEM), fourier-transform infrared spectroscopy (FTIR), and ultraviolet–visible spectroscopy analysis were used to characterize AuNPs. The TEM images show a spherical morphology for AuNPs with the range size of 21 to 59 for the synthetic nanoparticles. In the antioxidant test, the IC50 of AuNPs and butylated hydroxytoluene (BHT) against DPPH free radicals were 117 and 87 µg/mL, respectively. In the oncological part of the recent study, the treated cells with AuNPs and Cytarabine were assessed by MTT assay for 48 h about the cytotoxicity and anti-leukemia properties on normal (HUVEC) and leukemia cell lines i.e., acute myeloid leukemia (Human HL-60/vcr and 32D-FLT3-ITD), acute lymphoblastic leukemia (MOLT-3 and TALL-104), and acute T cell leukemia (J.RT3-T3.5 and Jurkat, Clone E6-1). The IC50 of AuNPs were 242, 297, 383, 207, 234, and 218 µg/mL against acute myeloid leukemia (Human HL-60/vcr and 32D-FLT3-ITD), acute lymphoblastic leukemia (MOLT-3 and TALL-104), and acute T cell leukemia (J.RT3-T3.5 and Jurkat, Clone E6-1) cell lines, respectively.

Recently, the development of carbon nanocomposites composed of carbon nanotubes and metal nanoparticles has attracted many interests because of their large potential for technological applications such as catalysts, sensors, biomedicine, and disinfection. In the present study, we described a simple chemistry method to synthesize multi-walled carbon nanotubes (MWCNTs) decorated with silver nanoparticles (Ag-NPs). Also, we investigated the antioxidant and anti-acute leukemia activities against acute myeloid leukemia and acute T cell leukemia cell lines. Ag NPs-MWCNTs were characterized and analyzed using common nanotechnology techniques including transmission electron microscopy (TEM), X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDS), field emission-scanning electron microscopy (FE-SEM) and elemental mapping analysis. Also, 2,2-diphenyl-1-picrylhydrazyl (DPPH) test was performed to assess the antioxidant capacities of AgNO₃, MWCNTs, and Ag NPs-MWCNTs. It revealed similar antioxidant potentials for Ag NPs-MWCNTs and butylated hydroxytoluene. In MTT assay, Ag NPs-MWCNTs had very low cell viability (very high anti-acute leukemia properties) dose-dependently against 32D-FLT3-ITD (Acute myeloid leukemia cell line), Human HL-60/vcr (Acute myeloid leukemia cell line), Jurkat, Clone E6–1 (Acute T cell leukemia cell line), and J.RT3-T3.5 (Acute T cell leukemia cell line) without any cytotoxicity on human umbilical vein endothelial cell line (HUVEC; Normal cell line). In conclusion, the synthesized Ag NPs-MWCNTs revealed excellent antioxidant and cytotoxicity activities against acute myeloid leukemia and acute T cell leukemia cell lines in a dose depended manner. After confirming in the in vivo and clinical trials, these nanoparticles can be administrated in humans for the treatment of acute leukemia especially acute myeloid leukemia and acute T cell leukemia.     

Preparation and synthesis a new chemotherapeutic drug of silver nanoparticle-chitosan composite; Chemical characterization and analysis of their antioxidant,cytotoxicity, and anti-acute myeloid leukemia effects in comparison to Daunorubicin in a leukemic mouse model

Nanoparticles usually have better outcomes than the bulk samples of the same element because they possess a higher specificity level than the larger particles. This is also true for silver nanoparticles, and little amount of these materials has high remedial effects. Silver nanoparticles are used as a therapeutic tool for the treatment of several diseases such as cancer. In this study, silver nanoparticles using chitosan (AgNPs-chitosan composite) are reported for the first time to exert a dietary therapeutic potential compared to Daunorubicin in an animal model of acute myeloid leukemia. The synthesized AgNPs-chitosan composite was characterized using different techniques including ultraviolet–visible spectroscopy, fourier-transform infrared spectroscopy, energy dispersive X-ray spectrometry, scanning electron microscopy, and transmission electron microscopy. FTIR findings suggested antioxidant compounds in the nanoparticles were the sources of reducing power, reducing silver ions to AgNPs. SEM and TEM images exhibited a uniform spherical morphology and average diameters of 30 nm for the nanoparticles. Then, 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging test was done to evaluate the antioxidant potentials of Daunorubicin, AgNO₃, chitosan, and AgNPs-chitosan composite. DPPH test revealed similar antioxidant potentials for Daunorubicin and AgNPs-chitosan composite. For the analyzing of cytotoxicity effects of Daunorubicin, AgNO₃, chitosan, and AgNPs, 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromidefor (MTT) assay was used on HUVEC, 32D-FLT3-ITD, and Murine C1498 cell lines. AgNPs-chitosan composite similar to Daunorubicin had low cell viability dose-dependently against 32D-FLT3-ITD and Murine C1498 cell lines without any cytotoxicity on HUVEC cell line. In vivo design, induction of acute myeloid leukemia was done by 7,12-Dimethylbenz[a]anthracene in 50 mice. Then, the animals were randomly divided into six subgroups, including control, untreated, Daunorubicin, AgNO₃, chitosan, and AgNPs-chitosan composite. Similar to Daunorubicin, AgNPs-chitosan composite significantly (P ≤ .01) decreased the weight of the body, the pro-inflammatory cytokines, and the total white blood cells, blast, neutrophil, monocyte, eosinophil, and basophil counts and increased the anti-inflammatory cytokines and the lymphocyte, platelet, and red blood cell parameters as compared to the untreated mice. These results show that the inclusion of chitosan improves the therapeutic properties of AgNPs-chitosan composite, which led to a significant enhancement in the antioxidant, cytotoxicity, and anti-acute myeloid leukemia activities of the nanoparticles. It appears that AgNPs-chitosan composite can be used as a chemotherapeutic drug for the treatment of acute myeloid leukemia in the clinical trial.

Oak gum mediated green synthesis of silver nanoparticles under ultrasonic conditions: Characterization and evaluation of its antioxidant and anti-lung cancer effects

Herein, we represent the bio-synthesis of silver nanoparticles (Ag NPs) employing Oak gum as the green template, an efficient natural and non-toxic reductant and stabilizer based on its phytochemicals by using ultrasonic irradiation. The characterization of as-synthesized Ag NPs was performed through Fourier transformed infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDS), elemental mapping, UV–Vis and X-ray diffraction (XRD). After the characterization, the synthesized Ag NPs/O. Gum was engaged in biological assays like study of anti-oxidant properties by DPPH mediated free radical scavenging test using MeOH and BHT as reference molecules. Thereafter, on having a significant IC₅₀ value in radical scavenging assay, we extended the bio-application of the desired nanocomposite in anticancer study of A549, Calu6 and H358 human lung cell lines in-vitro through MTT assay. They had very low cell viability and high anti-human lung cancer activities dose-dependently against the cell lines without any cytotoxicity on the normal cell line (MRC-5). The IC₅₀ of Ag NPs/O. Gum was found 161.25, 289.26 and 235.29 µg/mL against A549, Calu6 and H358 cell lines, respectively. Maybe significant anti-human lung cancer potentials of Ag NPs/O. Gum against common lung cancer cell lines are related to their antioxidant activities. So, these results suggest that synthesized Ag NPs/O. Gum as a chemotherapeutic nanomaterial have a suitable anticancer activity against lung cell lines.

The in vitro antibacterial and antifungal studies demonstrated the DB-AuNPs and DB-AgNPs have good antibacterial activity against E. coli and other livestock pathogens, including Y. pseudotuberculosis and S. typhi. Cell studies revealed that the higher concentrations of both DB-AuNPs and DB-AgNPs (1 µg/ml to 1 mg/ml) showed potent cytotoxicity in chicken cells after 24 hrs, whereas the middle and lower concentrations of DB-AuNPs and DB-AgNPs did not show cytotoxicity in selected cell lines after 24 hrs. In addition, the DB synthesized AuNPs and AgNPs exhibited good free scavenging activity in a dose-dependent manner. Therefore, the biosynthesized nanoparticles can be utilized by the livestock industry to develop an effective source against livestock microbial infections.     

Green supported Cu nanoparticles on modified Fe3O4 nanoparticles using thymbra spicata flower extract: Investigation of its antioxidant and the anti-human lung cancer properties

In recent days, the green synthesized nanomagnetic biocomposites have been evolved with tremendous potential as the future biological agents. This has encouraged us to design and synthesis of a novel Cu NPs supported Thyme flower extract modified magnetic nanomaterial (Fe₃O₄/Thyme-Cu). It was meticulously characterized using advanced analytical techniques like FT-IR, FESEM, TEM, EDX, VSM, XRD and ICP-OES. After the characterization, the synthesized Fe₃O₄/Thyme-Cu nanocomposite was engaged in biological assays like study of anti-oxidant properties by DPPH mediated free radical scavenging test using BHT as a reference molecule. Thereafter, on having a significant IC50 value in radical scavenging assay, we extended the bio-application of the desired nanocomposite in anticancer study of A549, Calu6 and H358 human lung cell lines in-vitro through MTT assay. They had very low cell viability and high anti-human lung cancer activities dose-dependently against A549, Calu6 and H358 cell lines without any cytotoxicity on the normal cell line (MRC-5). The IC50 of Fe₃O₄/Thyme-Cu nanocomposite was 124, 265, and 181 µg/mL against A549, Calu6 and H358 cell lines, respectively. Maybe significant anti-human lung cancer potentials of Fe₃O₄/Thyme-Cu nanocomposite against common lung cancer cell lines are related to their antioxidant activities. So, these results suggest that synthesized Fe₃O₄/Thyme-Cu nanocomposite as a chemotherapeutic nanomaterial have a suitable anticancer activity against lung cell lines.     

Green synthesis of Ag/Fe3O4 nanoparticles using Mentha extract: Preparation,characterization and investigation of its anti-human lung cancer application

In this study, silver nanoparticles (Ag NPs) were decorated on the surface of magnetic nanoparticles in an eco-friendly pathway applying Mentha extract as reducing/stabilizing agent. The morphological and physicochemical features of the prepared Ag/Fe₃O₄nanocomposite were determined using several advanced techniques. Hence, our protocol is green and advantageous in terms of- i) biochemical modified biocompatible nanocomposite; ii) nanomaterial providing high surface area and larger number reactive sites; iii) very simplistic synthetic procedure; vi) very low load of metal in the composite and v) high yield in short time. In the medicinal part, the anticancer properties of Ag/Fe₃O₄ nanocomposite against lung cancer cell lines were determined. The free radical for the antioxidant effects was DPPH. The IC₅₀ of Ag/Fe₃O₄ nanocomposite was 200 µg/ml in the antioxidant test. The IC₅₀ of the Ag/Fe₃O₄ nanocomposite were 183, 176, 169, and 125 µg/mL against lung cancer (NCI-H661, NCI-H1975, NCI-H1573, and NCI-H1563) cell lines, respectively. In addition, the current study offer that Ag/Fe₃O₄ nanocomposite could be a new potential adjuvant chemopreventive and chemotherapeutic agent against cytotoxic cells.     

Pectin mediated green synthesis of Fe3O4/Pectin nanoparticles under ultrasound condition as an anti-human colorectal carcinoma bionanocomposite

This work described the one-pot synthesis of apple pectin encapsulated Fe₃O₄ nanoparticles (Fe₃O₄/Pectin NPs) which is prepared by co-precipitation of Fe(II/(III) ions in alkaline solution mediated by pectin under ultrasound condition. This process led to formation of magnetic nanoparticles within the network of pectin. Physicochemical characterization of the as-synthesized Fe₃O₄/Pectin NPs was carried out through electron microscopy (SEM and TEM), energy dispersive X-ray spectroscopy (EDX), vibrating sample magnetometer (VSM) and X-ray diffraction (XRD). The in vitro cytotoxic and anti-colorectal cancer effects of biologically synthesized Fe₃O₄/Pectin NPs against Ramos.2G6.4C10, HCT-8 [HRT-18], HCT 116, and HT-29 cancer cell lines were assessed. The anti-colorectal cancer properties of the Fe₃O₄/Pectin NPs could significantly remove Ramos.2G6.4C10, HCT-8 [HRT-18], HCT 116, and HT-29 cancer cell lines in a time and concentration-dependent manner by MTT assay. The IC₅₀ of the Fe₃O₄/Pectin NPs were 317, 337, 187, and 300 µg/mL against Ramos.2G6.4C10, HCT-8 [HRT-18], HCT 116, and HT-29 cancer cell lines. The antioxidant activity of Fe₃O₄/Pectin NPs was determined by DPPH method. The Fe₃O₄/Pectin NPs showed the high antioxidant activity according to the IC₅₀ value. It seems that the anti-human colorectal cancer effect of recent nanoparticles is due to their antioxidant effects.     

Physico-chemical characterization and anti-laryngeal cancer effects of the gold nanoparticles

Most recently, gold nanoparticles due to anticancer properties have been considered in medical science. So the aim of the study was green synthesis of gold nanoparticles using Ocimum basilicum extract and its anticancer activity. The prepared Au nanoparticles were characterized by advanced physicochemical techniques like Fourier Transformed Infrared spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Energy Dispersive X-ray spectroscopy (EDX), X-ray Diffraction (XRD) and UV–vis spectroscopy study. It has been established that Au nanoparticles have a spherical shape with a mean diameter from 19 to 44 nm. In the cellular and molecular part of the recent study, the treated cells with Au nanoparticles were assessed by MTT assay for 48 h about the cytotoxicity and anti-human laryngeal cancer properties on normal (HUVEC) and cancer (HEp-2, TU212, KB, UM-SCC-5, UM-SCC-11A and UM-SCC-11B) cell lines. In the antioxidant test, the IC50 of Au nanoparticles and BHT against DPPH free radicals were 228 and 208 µg/mL, respectively. The IC50 of Au nanoparticles were 174, 231, 179, 143, 230, and 216 µg/mL against HEp-2, TU212, KB, UM-SCC-5, UM-SCC-11A and UM-SCC-11B cell lines, respectively. The viability of malignant cell lines reduced dose-dependently in the presence of Au nanoparticles. It appears that the anti-cancer effect of Au nanoparticles e to their antioxidant effects.
