Synthesis, Molecular Docking Studies and In Silico ADMET Screening of New Heterocycles Linked Thiazole Conjugates as Potent Anti-Hepatic Cancer Agents

Thiazoles are important scaffolds in organic chemistry. Biosynthesis of thiazoles is considered to be an excellent target for the design of novel classes of therapeutic agents. In this study, a new series of 2-ethylidenehydrazono-5-arylazothiazoles - and 2-ethylidenehydrazono-5-arylazo- thiazolones - were synthesized via the cyclocondensation reaction of the appropriate hydrazonyl halides - and - with ethylidene thiosemicarbazide , respectively. Furthermore, the thiosemicarbazide derivative was reacted with different bromoacetyl compounds - to afford the respective thiazole derivatives - . Chemical composition of the novel derivatives was established on bases of their spectral data (FTIR, H-NMR, C-NMR and mass spectrometry) and microanalytical data. The newly synthesized derivatives were screened for their in vitro anti-hepatic cancer potency using an MTT assay. Moreover, an in silico technique was used to assess the interaction modes of the compounds with the active site of Rho6 protein. The docking studies of the target Rho6 with the newly synthesized fourteen compounds showed good docking scores with acceptable binding interactions. The presented results revealed that the newly synthesized compounds exhibited promising inhibition activity against hepatic cancer cell lines (HepG2).
