Abstract
Irradiation of mixtures of title diazonium salts and heteroarenes with green light (510 nm) in the presence of eosin Y disodium salt (EY-Na2) as a photocatalyst furnished the corresponding arylation products in 8-63% yields. The proposed photocatalytic cycle is analogous to that proposed previously for closely related photoredox C-H arylations with aryl diazonium salts as aryl radical sources. This method has a broad substrate scope and represents a metal-free alternative for the synthesis of 3-heteroaryl-substituted 4H-quinolizin-4-ones and azino- and azolo-fused pyrimidones with a bridgehead nitrogen atom.

Abstract
Innate inflammation beyond a threshold is a significant problem involved in cardiovascular diseases, cancer, and many other chronic conditions. Cyclooxygenase (COX) enzymes are key inflammatory markers as they catalyze prostaglandins production and are crucial for inflammation processes. While COX-I is constitutively expressed and is generally involved in "housekeeping" roles, the expression of the COX-II isoform is induced by the stimulation of different inflammatory cytokines and also promotes the further generation of pro-inflammatory cytokines and chemokines, which affect the prognosis of various diseases. Hence, COX-II is considered an important therapeutic target for drug development against inflammation-related illnesses. Several selective COX-II inhibitors with safe gastric safety profiles features that do not cause gastrointestinal complications associated with classic anti-inflammatory drugs have been developed. Nevertheless, there is mounting evidence of cardiovascular side effects from COX-II inhibitors that resulted in the withdrawal of market-approved anti-COX-II drugs. This necessitates the development of COX-II inhibitors that not only exhibit inhibit potency but also are free of side effects. Probing the scaffold diversity of known inhibitors is vital to achieving this goal. A systematic review and discussion on the scaffold diversity of COX inhibitors are still limited. To address this gap, herein we present an overview of chemical structures and inhibitory activity of different scaffolds of known COX-II inhibitors. The insights from this article could be helpful in seeding the development of next-generation COX-II inhibitors.

Abstract
Abstract:
A series of novel amide and Schiffs base functionalized novel pyrido[1,2-a] pyrimidin-
4-one derivatives was prepared starting from 6-(thiophen-2-yl)/phenyl-4-(trifluoromethyl) pyridin-
2-amine 1a and 1b. These compounds on reacting with EMME afford compounds 2a and 2b,
followed by cyclization to afford compounds 3a and 3b. Treatment of compounds 3a and 3b with
hydrazine hydrate gave compounds 4a and 4b, which further reacted with different substituted aromatic
aldehydes to give Schiff’s base derivatives 5a-j. In another way, compounds 3a, 3b by reacting
with aliphatic amines give amide derivatives 6a-f. All the compounds, 5a-j and 6a-f, were
screened against four human cancer cell lines (HeLa, COLO205, Hep G2, and MCF 7). Among all
the derivatives, compounds 5c, 5e, 6a, and 6b showed promising anticancer activity.

Abstract
Kynurenic acid (KYNA) is an endogenous neuroprotective agent of increasing importance. Several derivatives have already been synthesized, bearing an abundance of functional groups attached to the main skeleton in different positions. Several of these compounds have already been tested in biological evaluations, with several of them targeting the same receptors and biological effects as KYNA. However, these modified compounds build upon the unmodified KYNA skeleton leaving a possible route for the synthesis of new, potentially neuroprotective derivatives with heteroatom-containing ring systems. The aim of this review is to summarize the syntheses of KYNA derivatives with altered skeletons and to pinpoint an appealing transformation for future medicinal lead molecules.

Abstract
Heterocyclic compounds constitute a unique class of organic compounds endowed with a wide range of synthetic and pharmaceutical applications. Pyrimidinones and their fused analogues have received focused attention in this regard, partly due to their mimicry of nucleobases which consequently forges their interesting medicinal properties. Over the years, the medicinal chemistry research community has experienced an upsurge in articles describing the exploration of these scaffolds to develop effective therapeutic agents. Several biological activities, including antimicrobial, antiviral, anticancer, antidiabetic, anti-inflammatory, anticonvulsive, and antihistaminic, have been well documented. This minireview presents a compendium of recent developments (2017-2020) focused on the synthesis and biological activities of fused pyrimidinones. The goal is to update medicinal chemists on the therapeutic relevance of fused pyrimidinones and the molecular architecture of clinic-worthy drug candidates. A brief account of the structure-activity relationships (SAR) revealed from different biological assays is also discussed.

Abstract
Resveratrol is a non-flavonoid polyphenol containing a terpenoid backbone. It has been intensively studied because of its various promising biological properties, such as anticancer, antioxidant, antibacterial, neuroprotective and anti-inflammatory activities. However, the medicinal application of resveratrol is constrained by its poor bioavailability and stability. In the past decade, more attention has been focused on making resveratrol derivatives to improve its pharmacological activities and pharmacokinetics. This review covers the literature published over the past 15 years on synthetic analogues of resveratrol. The emphasis is on the chemistry of new compounds and relevant biological activities along with structure-activity relationship. This review aims to provide a scientific and reliable basis for the development of resveratrol-based clinical drugs.
