The purpose of the research is to synthesise a novel series of (E)-2-(4-(1H-indol-3-yl)-6-p-substituted phenylpyrimidin-2-yl)dimethylguanidine derivatives since 3-(1H-indol-3-yl)-1-p-substituted phenylprop-2-en-1-one and evaluate their molecular docking studies, antimicrobial, and anti-diabetic activities. Among all the synthesized compounds (11a-g), compound 11a exhibits excellent CDOCKER energy (−11.36 kcal/mol). The entire compounds (11a-g) confirm very good antimicrobial activity towards the tested microorganisms. In the in vitro anti-diabetic studies, compounds (11a, 11c, and 11g) confirm higher alpha-amylase and alpha-glucosidase inhibition activity. In the in vivo anti-diabetic activities, the synthesized compounds (11a-g) (10 mg/kg, p.o.) investigated by the streptozotocin (60 mg/kg, ip) –nicotinamide (120 mg/kg, p.o.) – induced model in adult male albino Wistar rat and these derivatives show considerable fasting blood glucose level when compared to metformin hydrochloride a potent and well-known anti-diabetic drug as a reference.
