Regarding the critical role of amyloid-β plaques in the pathogenesis of Alzheimer's disease, a series of aminoimidazo[1,2-a]pyridine derivatives were designed and synthesized as potential anti-BACE1 agents targeting the production of amyloid-β plaques. In vitro biological results demonstrated that compounds 7b and 7f exhibited the best inhibitory potency against BACE1 with IC50 values of 22.48 ± 2.06 and 30.6 Read More

Aims: The aim of this present work was to design and establish an efficient synthesis of new thienyl pyrazolo[1,5128;a] pyrimidines using an environmentally friendly reaction solvent. Further, the newly synthesized compounds were evaluated for antimicrobial activity. Materials and Methods: A series of thienyl pyrazolo[1,5128;a] pyrimidines have been synthesized by the condensation reaction of 4128;(4’128;chloro1 Read More

Background: Thiazole-containing compounds are widely found in natural products as well as synthetic sources. Many thiazole-based compounds possess a broad spectrum of bioactivities, and some of them are well-known drugs in the markets. The use of thiazole derivatives in other fields such as organic materials, cosmetics, and organic synthesis has also been widely reported. Due to a wide range of applicability, the synt Read More

Rational design and synthesis of novel compounds with both effectivity and safety properties have always been a formidable task in the development of drugs. Oxadiazoles are heterocyclic bioscaffolds occurring as motifs in drug-like molecules. This review article highlights comprehensive and systematic information of compounds containing 1,2,4-oxadiazoles and 1,3,4-oxadiazole rings. The routes for the sy Read More

Objective: The current objective was to synthesize biologically active Isatin derivatives. For this purpose, six (06) chemical entities of Isatin derivatives such as 3a-3c and 4a-4c were synthesized from Isatin substrate. Methods: The pure compounds were characterized with the help of 1H-NMR, FT-IR, EIMS spectroscopic techniques. The synthesized amines 3a-3c and hydrazones 4a-4c were evaluated for their toxicity poten Read More

Aims: This study aimed at synthesizing, analyzing, and utilizing two new direct dyes based on chromene derivatives as the chromophoric moiety in dyeing wool, silk, and cotton, with good color strength, light fastness, and other desirable features. Background: New direct dyes with antimicrobial activities for Gram-positive, Gram-negative bacteria, and fungus are being developed. These dyes are used on cotton, silk, and wool ma Read More
