Abstract
C-N coupling reactions were found to be attractive among researchers owing to
the importance of C-N bond formation in heterocyclic synthesis. Hence C-N bond formation
via amination reaction with the assistance of microwave radiations gained significant
attraction recently. Microwave-assisted reactions are greener, faster and generally efficient
compared to the conventional thermal reactions offering better purity of the product with
enhancement in the yield. It was surprisingly revealed that several new advancements in
amination reactions were highly influenced by this greener technology. This first review on
microwave-assisted amination reaction focuses on the novel amination strategies that
emerged with the help of microwave methodology, and covers literature up to 2019.

Cyclic bridged analogs of isoCA-4: Design, synthesis and biological evaluation. Eur J Med Chem 2020; 209:112873. [PMID: 33038796 DOI: 10.1016/j.ejmech.2020.112873] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2020] [Revised: 09/21/2020] [Accepted: 09/21/2020] [Indexed: 12/14/2022]
Abstract
In this work, a series of cyclic bridged analogs of isocombretastatin A-4 (isoCA-4) with phenyl or pyridine linkers were designed and synthesized. The synthesis of the desired analogs was performed by the formation of nitro-vinyl intermediates, followed by a Cadogan cyclization. Structure activity relationship (SAR) study demonstrates the critical role of the combination of quinaldine as ring A, pyridine as the linker, and indole as ring B in the same molecule, for the cytotoxic activity. Among all tested compounds, compound 42 showed the highest antiproliferative activity against a panel of cancer cell lines with average IC50 values of 5.6 nM. Also, compound 42 showed high antiproliferative activity against the MDR1-overexpressing K562R cell line; thus, it was 1.5- and 12-fold more active than the reference compounds, isoCA-4 and CA-4, respectively. Moreover, 42 displayed a strong antiproliferative activity against the colon-carcinoma cells (HT-29), which are resistant to combretastatin A-4 and isoCA-4, and it was found to be 8000-fold more active than natural CA-4. Compound 42 also effectively inhibited tubulin polymerization both in vitro and in cells, and induced cell cycle arrest in G2/M phase. Next, we demonstrated that compound 42 dose-dependently caused caspase-induced apoptosis of K562 cells through mitochondrial dysfunction. Finally, we evaluated the effect of compound 42 in human no cancer cells compared to the reference compound. We demonstrated that 42 was 73 times less cytotoxic than isoCA-4 in quiescent peripheral blood lymphocytes (PBLs). In summary, these results suggest that compound 42 represents a promising tubulin inhibitor worthy of further investigation.
