Development and progress of cancer is a very complex disease process to comprehend because of the multiple changes in cellular physiology, pathology, and pathophysiology resulting from the numerous genetic changes from which cancer originates. As a result, most common treatments are not directed at the molecular level but rather at the tissue level. While personalized care is becoming an increasingly aim, the most common cancer treatments are restricted to chemotherapy, radiation, and surgery, each of which has a high likelihood of resulting in rather severe adverse side effects. For example, currently used radiation therapy does not discriminate between normal and cancerous cells and greatly relies on the external targeting of the radiation beams to specific cells and organs. Because of this, there is an immediate need for the development of new and innovative technologies that help to differentiate tumor cells and micrometastases from normal cells and facilitate the complete destruction of those cells. Recent advancements in nanoscience and nanotechnology have paved a way for the development of nanoparticles (NPs) as multifunctional carriers to deliver therapeutic radioisotopes for tumor targeted radiation therapy, to monitor their delivery, and improve the therapeutic index of radiation and tumor response to the treatment. The application of NPs in radiation therapy has aimed to improve outcomes in radiation therapy by increasing therapeutic effect in tumors and reducing toxicity on normal tissues. Because NPs possess unique properties, such as preferential accumulation in tumors and minimal uptake in normal tissues, it makes them ideal for the delivery of radiotherapy. This review provides an overview of the recent development of NPs for carrying and delivering therapeutic radioisotopes for systemic radiation treatment for a variety of cancers in radiation oncology. 相似文献

A clean and efficient Michael addition reaction on chalcones using phosphonium ionic liquid catalyst (PhosIL-Cl) is described. The method provides several advantages, such as simple workup, environmental friendliness, mild conditions, and excellent yields. In addition, the ionic liquid was chosen as a green solvent, recovered, and reused several times in subsequent reactions. 相似文献

The scope of nickel boride as a versatile reducing reagent is extended to the 3-oxidopyrylium-alkene [5 + 2] cycloadducts. In this report, we demonstrate that nickel boride is capable of one-pot 1,2- and 1,4-reduction of enones present in the cycloadducts in good yields. Subsequent elaboration of the cycloadducts towards synthesis of functionalized cycloheptenoid derivatives devoid of the oxa-bridge is also explored.

A metal–organic framework (MOF)‐based catalyst, chromium hydroxide/MIL‐101(Cr), was prepared by a one‐pot synthesis method. The combination of chromium hydroxide particles on and within Lewis acidic MIL‐101 accomplishes highly selective conversion of glucose to fructose in the presence of ethanol, matching the performance of optimized Sn‐containing Lewis acidic zeolites. Differently from zeolites, NMR spectroscopy studies with isotopically labeled molecules demonstrate that isomerization of glucose to fructose on this catalyst, proceeds predominantly via a proton transfer mechanism. 相似文献

A one-pot, synthesis of N-arylsulfonyl-2-iminocoumarins is developed at ambient temperature by the reaction of 2-hydroxybenzaldehydes, arylacetonitriles, and aryl sulfonyl chlorides using DABCO as a base in a bio-mass-derived green solvent 2-MethylTHF. A simple telescoped process in which 2H-chromen-2-imines are formed in situ by the condensation of 2-hydroxybenzaldehyde and arylacetonitriles. The formed imines are further reacted with arylsulfonyl chlorides in a one-pot approach to obtain the target compounds. This protocol provides access to 3-aryl-N-arylsulfonyl-2-iminocoumarins in a practical and environmentally benign way avoiding cumbersome steps of intermediate syntheses and purifications. 相似文献
