Status of Drug Discovery Research Based on Marine Organisms from Eastern Indonesia

Despite the vastness of Eastern Indonesian Waters (EIW), no review has been done on the status of drug discovery research based on marine organisms from this area. The aim of this paper is to briefly discuss the challenges and perspectives on drug discovery research based on marine organisms in these indigenous waters. The emphasis is on the last 20 year period (1993 to 2013). Research activities completed during this period suggest that marine organisms from EIW could be utilized as an important natural resource for future drug discovery and development. However, lack of facilities, as well as competent human resources, significantly hinder progress on drug discovery research. More in-depth study especially on deep-sea natural products needs to be carried out to solidify the research on the potential for marine organisms from EIW to contribute to the future of drug discovery.

A closer look on various synthetic routes to Callystatin A: a cytotoxic marine sponge polyketide

Callystatin A, a polyketide marine natural product, has been known since 1997 after its isolation from the sponge Callyspongia truncata by Kobayashi et al. It belongs to the leptomcyin family of natural products with a highly conjugated and stereodefined skeleton. The challenging structural topographies and remarkable anti-proliferative properties of (?)-Callystatin A stimulated many researchers to pursue the total synthesis of this marine polyketide. This review is exclusively focused on the research undertaken towards the concise, asymmetric total synthesis of Callystatin A over the last two decades. The various target oriented synthetic pathways are discussed in a chronological order to give a comprehensive overview.     

A brief review of potent anti-CNS tumourics from marine sponges: covering the period from 1994 to 2014

This review covers the 1994–2014 literature data published for anti-CNS tumour natural products isolated from marine sponges. The focus was on highly potent antitumourics. It describes only eight promising bioactives (screened on even less number of the respective cell lines) suggesting that brain tumours actually represent quite a hot topic for the natural product research community worldwide.     

Merging the potential of microbial genetics with biological and chemical diversity: an even brighter future for marine natural product drug discovery

Marine invertebrates and a growing number of marine bacteria are the sources of novel, bioactive secondary metabolites. Structurally, many of these compounds appear to be biosynthesized by polyketide synthases (PKS) and/or nonribosomal peptide synthetases (NRPS) that have also been found in terrestrial microbes. This review highlights scientific advances from 1999-2003 in the emerging field of molecular genetics of polyketide and nonribosomal peptide natural products isolated from marine organisms. The implications of this research towards the development of marine secondary metabolites as a sustainable source of new drugs are discussed.

Highlights of marine natural products chemistry (1972-1999)

Marine Natural Products Chemistry is essentially a child of the 1970's that developed rapidly during the 1980's and matured in the last decade. With a few notable exceptions, it is difficult to select individual papers that significantly impacted the field. However, marine natural products chemistry has often influenced other fields and that aspect is the focus of this review. It is clear that the early directions taken by marine natural products chemists drew as much from the examples provided by insect chemical ecology as from the longer history of phytochemistry. By 1975 there were already three parallel tracks in marine natural products chemistry: marine toxins, marine biomedicinals and marine chemical ecology. It is the integration of the three fields of study that has given marine natural products chemistry its unique character and vigour.
