This study aims to design some dual-target anticancer candidates, capable to act as an alkylating agent as well as a thymidylate synthase (TS) inhibitor. The designed scaffold is a combination of nucleobase, amino acid and aziridine structures. The candidates are docked into TS and three DNA double strand structures and evaluated based on their binding interaction energies and ligand efficienci...

Covalent grafting of MCM-41 with 3-chloropropyl trimethoxysilane and subsequent reaction respectively with acacdien and complexation with MoO2(acac)2 afforded MoO2acacdien@MCM-41. X-ray diffraction and nitrogen sorption analyses revealed the preservation of the textural properties of the support as well as accessibility of the channel system despite sequential reduction in surface area, pore vo...

Current researches have showed that N3, N5-diaryl-2, 6-dimethyl -1, 4-dihydropyrine-3, 5- dicarboxamide analogues demonstrate notable anti-tubercular activity. In this study, Hantzsch condensation was used to design and synthesize new analogues of dihydropyridine (DHP). Different diary carboxamides were inserted at positions 3 and 5 of the DHP ring. 4(5)-chloro-2-ethyl-5(4)-imidazolyl moiety wa...

Superoxide dismutase play important roles in iron-respiratory bacteria such as Geobacteraceae as an antioxidant defense, and probably an effective enzyme of electron transfer network. Regarding the application of iron-respiratory bacteria in environmental biotechnology particularly biodegradation and bioremediation, understanding the mechanism of inhibition/induction of superoxide dismutase by ...
