Mitochondria are pivotal energy production sources for cells to maintain necessary metabolism activities. Targeting dysfunctional mitochondrial features has been a hotspot for mitochondrial-related disease researches. Investigation with cancerous mitochondrial metabolism is a continuing concern within tumor therapy. Herein, we set out to assess the anti-cancer activities of a novel family of TPP-thiazole derivatives based on our earlier research on mitochondrial targeting agents. Specifically, we designed and synthesized a series of TPP-thiazole derivatives and revealed by the MTT assay that most synthesized compounds effectively inhibited three cancer cell lines (HeLa, PC3 and MCF-7). After structure modifications, we explored the SAR relationships and identified the most promising compound R13 (IC50 of 5.52 μM) for further investigation. In the meantime, we performed ATP production assay to assess the selected compounds inhibitory effect on HeLa cells energy production. The results displayed the test compounds significantly restrained ATP production of cancer cells. Overall, we have designed and synthesized a series of compounds which exhibited significant cytotoxicity against cancer cells and effectively inhibited mitochondrial energy production.

The efficient synthesis of 2-substituted thiazoles and benzothiazoles has been accomplished employing readily available cysteine esters and 2-aminobenzenethiols as N and S sources. The reaction proceeds under an I2/TBHP system and involves a on

A series of 2-adamantyl-5-arylthiazolyl-1,3,4-oxadiazoles 7a–x together with thiazoles 13 and 14 were synthesized. Compounds 7a–l, 13, and 14 were tested in vitro with the aim of identifying novel lead compounds active against human immunodeficiency virus type-1 and human immunodeficiency virus type-2 activity in MT-4 cells. Title compounds were also tested against representatives of Gram-positive and Gram-negative bacteria (Staphylococcus aureus, Salmonella spp.), various mycobacterial strains (Mycobacterium fortuitum and Mycobacterium smegmatis), yeast (Candida albicans), and mold (Aspergillus fumigatus). None of the compounds showed antiviral or antimicrobial activity, except compounds 13 and 14 exhibited anti-human immunodeficiency virus-1 activity with EC50 values of 1.79 and 2.39 μM with Selectivity index = 18 and 4, respectively. On the other hand, compounds 7a and 7j showed a marked cytotoxicity against the human CD4+ lymphocytes (MT-4). Therefore, 7a and 7j were evaluated for their antiproliferative activity against two solid tumor-derived cell lines, which exhibited IC50 values of 8.1 ± 0.10 μM and 4.8 ± 0.08 μM against Hep-G2 cell lines, respectively.
New Aryl-1,3-thiazole-4-carbohydrazides, Their 1,3,4-Oxadiazole-2-thione, 1,2,4-Triazole, Isatin-3-ylidene and Carboxamide Derivatives. Synthesis and Anti-HIV Activity

A series of isatin-3-ylidene (6a-i) and arylthiazolyl-1,3,4-oxadiazole-2- thione derivatives 7a-i derived from arylthiazolyl carbohydrazide analogs 4a-i were synthesized. Analogously, coupling of 4f with various amino acid methyl esters in the presence of HOBt/DCC reagents afforded the carboxamide derivatives 9a-d. The newly synthesized compounds were assayed against HIV-1 and HIV-2 in MT-4 cells. All compounds are inactive, except compounds 9b and 9c which showed inhibition of HIV-1 with EC50 = 2:34 μgmL-1, and 1.12 μgmL-1 with therapeutic indexes (SI) of 9 and 1, respectively.

Two-dimensional libraries of 4-acylamino-1,3-thiazoles 9 were prepared via Curtius rearrangement of 1,3-thiazole-4-carbonyl azides 6, trapping of the intermediate isocyanates with oxime resin, and thermal regeneration of the isocyanates from the washed resin in the presence of nucleophiles. Several compounds proved to be selective inhibitors of CDK5/p25 versus the closely homologous CDK2/cyclin A enzyme, with the best analogue (43) possessing over 100-fold selectivity.
