The present work describesthe development of highly potent mushroom tyrosinase inhibitor better than the standard kojic acid. Carvacrol derivatives 4a-f and 6a-d having substituted benzoic acid and cinnamic acidresidues were synthesized with the aim to possess potent tyrosinase inhibitory activity.The structures of the synthesized compounds were ascertained(More)
Methicillin resistant Staphylococcus aureus (MRSA) is resistant to known antibiotics and has become a great challenge for healthcare professionals, therefore new molecules are needed to manage this situation. In this study, new lead molecules 4-Amino-5-(2-Hydroxyphenyl)-1,2,4-Triazol-3-Thione (U1) and4-(2-hydroxybenzalidine) amine-5-(2-hydroxy)(More)
A series of six novel benzimidazole-pyrazole hybrid molecules was synthesized and characterized using elemental analysis (CHN) and spectroscopic methods (1HNMR, FT-IR). All the synthesized compounds were evaluated for their in vivo anti ulcerogenic activity using Albino rats (weighing 180-220 g). The interactions between the compounds and active site(More)
4-Aminophenazone (Ap-1) Schiff bases i.e., 4-{(3,4,5-trimethoxybenzylidine) amino}phenazone (Ap-2), 4-{(2-chlorobenzylidine) amino}phenazone (Ap-3) and 4-{(4-chlorobenzylidine)amino} phenazone (Ap-4) were synthesized and characterized by different spectroscopic techniques. Interaction of these compounds with ds.DNA was investigated through UV-Visible(More)
Purpose: The triazole nucleus is an important part of the therapeutically interesting drug candidate as antimicrobial, analgesic, anticancer, anticonvulsant and anti-inflammatory agents. Methods: Therefore, in this study, twelve 4,5-disubstituted-1,2,4-triazole-3-thiols were synthesized by the reaction of substituted isothiocyanates and hydrazides using the(More)
The present work describes the synthesis of few hydroxylated amide derivatives as melanogenesis inhibitors. In vitro, in vivo and computational studies proved that compound 6d is a highly potent melanogenesis inhibitor compared to standard kojic acid. The title amides 4a-e and 6a-e were synthesized following simple reaction routes with excellent yields.(More)
Typhoid fever, caused by Salmonella typhi, is characterized by gastrointestinal illness and fatal bloody diarrhea. The emerging epidemic cases and resistance of this bacterium to broad spectrum antibiotics demands the development of new anti-typhoid drugs. In this study, oxadiazole has been synthesized with significant anti-Salmonella activity. This(More)
