In the present study, a total of 9 novel permethyl ningalin B analogs have been synthesized and evaluated for their P-gp modulating activity in a P-gp overexpressed breast cancer cell line LCC6MDR. Among these derivatives, compound 12 with dimethoxy groups at rings A and B and tri-substitution at ring C with ortho-methoxyethylmorpholine, meta-bromo and para-benzyloxy groups displays the most potent P-gp modulating activity with EC50 of 423 nM to reverse paclitaxel resistance. It is non-toxic towards L929 fibroblast with IC50 greater than 100 mu M and with selective index greater than 236. Its mechanism to reverse P-gp mediated drug resistance is by virtue of inhibiting transport activity of P-gp, restoring intracellular drug accumulation and eventually chemosensitizing the cancer cells to anticancer drug again. Moreover, compound 12 showed better solubility (405 ng/mL) than hit compound 1 in phosphate buffer (pH 4.0). In summary, our study demonstrates that permethyl ningalin B derivative 12 is non-toxic and efficient P-gp inhibitor that is a potential candidate to be used clinically to reverse P-gp mediated cancer drug resistance.

4-Imidazo[2,1-b]thiazole-1,4-DHPs and neuroprotection: preliminary study in hits searching
particular the strategy adopted for designing the compounds involves the imidazo[2,1-b]thiazole nucleus. The observed properties show that substituents at C2 and C6 of the bicyclic scaffold are able to influence the cardiovascular parameters and the neuroprotective activity. In comparison to nifedipine, a set of derivatives such as compound 6, showed a neuroprotective profile of particular interest.
