Synthesis and antiproliferative activity of thiazolidine analogs for melanoma
摘要:
We have previously described 2-aryl-thiazolidine-4-carboxylic acid amides as a novel class of antiproliferative agents for prostate cancer. Screening these compounds with melanoma cell lines revealed that several of them have potent antiproliferative activity and selectivity against melanoma. To further improve the potency and selectivity, we synthesized a new series of analogs and tested them in two melanoma cell lines and fibroblast cells (negative controls). Comparison of anticancer effects of these compounds with a standard chemotherapeutic agent, sorafenib, showed that they are very effective in killing melanoma cells with low micromolar to nanomolar antiproliferative activity and provide us a new lead for developing potential drugs for melanoma.

The synthesis and antihypertensive activity of a new series of N-(mercaptoacyl)-thiazolidinecarboxylic acids (VIIa-d) are described. Antihypertensive activity was evaluated in terms of angiotensin I-converting enzyme (ACE) inhibitory activity. The activities of these compounds were compared with that of (2S)-1-[(2S)-3-mercapto-2-methylpropanoyl] proline, SQ 14225, and many of them were found to be relatively potent inhibitors of ACE. The most potent was (4R)-2-(2-hydroxyphenyl)-3-(3-mercaptopropanoyl)-4-thiazolidinecarboxylic acid (62). Structure-activity relationships among the thiazolidines and some related compounds are discussed.

good selectivity and potency against four prostate cancer cell lines (DU 145, PC-3, LNCaP, and PPC-1). The structure–activityrelationship (SAR) of the side chain, the thiazolidine ring, and phenyl substituents is discussed. Cell cycle analysis showed that the percentage of cancer cells undergoing apoptosis (sub-G1 phase) increased after treatment with 1b and 3ad, which also strongly inhibited melanoma

To improve the selectivity and antiproliferative activity of previously reported serine amide phosphates (SAPs), we designed a new series of 4-thiazolidinone amides, in which the 4-thiazolidinone moiety was introduced as a phosphate mimic. However, these 4-thiazolidinone derivatives demonstrated less cytotoxicity in prostate cancer cells despite improved selectivity over RH7777 cells. To further optimize the thiazolidinone analogues in terms of cytotoxicity and selectivity, we made closely related structural modifications, which led us to the discovery of a new class of 2-arylthiazolidine-4-carboxylic acid amides. These compounds were potent cytotoxic agents with IC50 values in the low micromolar concentration range and demonstrated enhanced selectivity in receptor-negative cells compared to SAPs and 4-thiazolidinone amides.
