Negative connotations associated with the use of (-)-nicotine has limited medicinal chemistry research in the area of nAChRs [5]. However, recent evidence suggests that a diversity of nAChR subunits exist, that each subtype may be involved in mediating specific neurochemical/behaviors, and that these subtypes have a defined pharmacology that may be selectively targeted [1]. (+/-)-Epibatidine, GTS-21 and ABT-418 differentially interact with nAChR subtypes to elicit a diversity of behavioral effects including analgesia, neuroprotection and cognitive enhancement. These agents therefore represent important new pharmacological probes to dissect the nAChR subtype(s) mediating specific pharmacological responses to nAChR activation.

The chemical, biological and ecological diversity of the marine ecosystem has contributed immensely in the discovery of extremely potent compounds that have shown potent activities in antitumor, analgesia, antiinflammatory, immunomodulation, allergy, anti-viral etc. The compounds of marine origin are diverse in structural class from simple linear peptides to complex macrocyclic polyethers. The recent advances in the sophisticated instruments for the isolation and characterization of marine natural products and development of high-throughput screening, have substantially increased the rate of discovery of various compounds of biomedical application. Didemnin was the first marine peptide that entered in human clinical trials in US for the treatment of cancer and other compounds such as dolastatin-10, soblidotin, didemnin B, ecteinascidin 743, girolline, aplidine, cryptophycins (also arenastatin A), bryostatin 1, ILX 651, kahalalide F, E7389, discodermolide, ES-285 (spisulosine), HTI-286 (hemiasterlin derivative), squalamine, KRN-7000, vitilevuamide, Laulimalide, Curacin A, diazonamide, peloruside A, eleutherobin, sarcodictyin, thiocoraline, salicylihalimides A, ascididemnin, CGX-1160, CGX-1007dictyodendrins, GTS-21 (aka DMBX), manoalide, IPL-576,092 (aka HMR-4011A) have entered in the clinical trials. This article summarize clinical status and synthetic advances of some of these compounds.
