Synthesis and ADMET Study of Some 1, 8-Naphthyidine and Quinoline 3-Carboxylic Acid Derivatives

The extremely drug resistant may be a worldwide public ill health in recent years. Molecules with newer targets and an alternate mechanism of action is an urgent requirement of improvement of latest drugs. The utilization of heterocyclic compounds has been increased dramatically over the last 70 years due to their wide selection of technical applications and their favorable environmental and toxicological properties The 1,8-naphthyridine and quinoline 3-carboxylic acid derivatives that we'll manufacture during this method will change the potency and specificity of fluoroquinolones. Taking under consideration the findings, the goal is to style and manufacture 1, 8-naphthyridine and quinoline 3-carboxylic acid derivatives. The synthesized compounds are going to be characterized using multiple analytical techniques, virtual screening, and in-silico ADME/T prediction.

Synthetic Approaches and Biological Significance of Oxazolone Moieties: A Review

Oxazolone is a five-membered heterocyclic compound which is also known as azlactone. It contains one oxygen and one nitrogen as heteroatoms, which exist in five isomeric forms, according to the carbonyl group's location and the double bonds such as: 5 (4)-oxazolones, 5 (2) – oxazolones, 2 (3)-oxazolones, 4 (5)-oxazolones, and 2 (5)-oxazolones. 5 (4)-oxazolones is the most important heterocyclic moiety among all isomeric form of oxazolones. It is classified into two classes: saturated and unsaturated oxazolones. It is synthesized by various synthetic routes. Oxazolones are reported to exhibit various pharmacological activities such as antimicrobial, anti-inflammatory, anticancer, anti-HIV, antiangiogenic, anticonvulsant, sedative, cardiotonic, antidiabetic activity, etc.

Multicomponent Approach for the Sustainable Syntheses of Pyrido[2,3-d]pyrimidine Scaffold

: Pyrido[2,3-d]pyrimidine is an N-fused heterocyclic compound formed by the ortho fusion of pyridine and pyrimidine ring. Pyrido[2,3-d]pyrimidines hold a prominent position in medicinal chemistry owing to their wide spectrum of biological activities like antiviral, antihistaminic, antibacterial, diuretic, anti-inflammatory, analgesic, anticonvulsive, antipyretic, etc. The extraordinary features of pyrido[2,3-d]pyrimidines make their synthesis a perpetual field of research. Moreover, the construction of elaborate biologically relevant moieties via a multicomponent approach has become a promising area of research, owing to the burgeoning ‘green chemistry drive’. Advances in the exploitation of proficient synthetic routes involving a multicomponent approach for the assembly of this scaffold are reported in this review.
