Abstract
Herein, we report a novel, rapid and efficient route to the spiroquinazolinone framework via an umpolung strategy mediated by molecular iodine. A library of functionalized spiroquinazolinone iodide salts was synthesized in moderate to good yields under ambient, metal-free and mild conditions. The current methodology opens up a new efficient and concise strategy for the construction of spiroquinazolinones.

Abstract
The multicomponent-multicatalyst reaction ((MC)2R) and visible-light catalysis have emerged as green and powerful strategies for achieving ideal syntheses. Here, we report the first example of a visible-light-induced approach toward spiroquinazolin(thi)ones. This (MC)2R features an eco-friendly energy source and solvent, metal-free catalysts, step- and atom-economy, a relay catalysis strategy, air as green oxidant, mild conditions, and easily accessible starting materials.

Abstract
We report an efficient iron-catalyzed cross-dehydrogenative coupling [4 + 2] annulation of secondary/tertiary anilines with quinazolinones to generate quinoline-spiroquinzolinones. The reaction proceeds smoothly with a relatively broad variety of functional groups, a cheap transition metal catalyst (FeCl3), and environmentally friendly oxidant (H2O2/O2) under mild reaction conditions. Creatively, N-methylanilines are employed for the first time for the cycloaddition as both methyl and methylene sources attached to the N atom of tetrahydroquinolines.

Abstract
The efficacy and synthetic versatility of asymmetric organocatalysis have contributed enormously to the field of organic synthesis since the early 2000s. As asymmetric organocatalytic methods mature, they have extended beyond the academia and undergone scale-up for the production of chiral drugs, natural products, and enantiomerically enriched bioactive molecules. This review provides a comprehensive overview of the applications of asymmetric organocatalysis in medicinal chemistry. A general picture of asymmetric organocatalytic strategies in medicinal chemistry is firstly presented, and the specific applications of these strategies in pharmaceutical synthesis are systematically described, with a focus on the preparation of antiviral, anticancer, neuroprotective, cardiovascular, antibacterial, and antiparasitic agents, as well as several miscellaneous bioactive agents. The review concludes with a discussion of the challenges, limitations and future prospects for organocatalytic asymmetric synthesis of medicinally valuable compounds.

Abstract
In bacterial and archaeal purine biosynthetic pathways, sixth step involves utilization of enzyme PurE, catalyzing the translation of aminoimidazole ribonucleotide to 4-carboxy-5-aminoimidazole ribonucleotide (CAIR) with carbon dioxide. The formation of CAIR takes place through an unstable intermediate N5-CAIR, played by two enzymes-N5-CAIR synthetase (PurK) and N5-CAIR mutase (PurE) that further catalyzes the reaction of N5-CAIR to CAIR. In this study, N5-CAIR mutase (PH0320) from Pyrococcus horikoshii OT3 (PurE) was considered. The three-dimensional structure of Pyrococcus horikoshii OT3 was modeled based on the structure of PurE from Escherichia coli. The modeled structure was subjected to molecular dynamics simulation up to 100 ns, and least energy structure from the simulation was subjected to virtual screening and induced fit docking to identify the best potent leads. A total of five best antagonists were identified based on their affinity and mode of binding leading with conserved residues Ser18, Ser20, Asp21, Ser45, Ala46, His47, Arg48, Ala72, Gly73, Ala75, and His77 promotes the activity of Ph-N5-CAIR mutase. In addition to molecular dynamics, absorption, digestion, metabolism, and excretion properties, binding free energy and density functional theory calculations of compounds were carried out. Based on analyses, compound from National Cancer Institute (NCI) database, NCI_826 was adjudged as the best potent lead molecule and could be suggested as the suitable inhibitor of N5-CAIR mutase.

Abstract
Human chymase is a very important target for the treatment of cardiovascular diseases. Using a series of theoretical methods like pharmacophore modeling, database screening, molecular docking and Density Functional Theory (DFT) calculations, an investigation for identification of novel chymase inhibitors, and to specify the key factors crucial for the binding and interaction between chymase and inhibitors is performed. A highly correlating (r = 0.942) pharmacophore model (Hypo1) with two hydrogen bond acceptors, and three hydrophobic aromatic features is generated. After successfully validating "Hypo1", it is further applied in database screening. Hit compounds are subjected to various drug-like filtrations and molecular docking studies. Finally, three structurally diverse compounds with high GOLD fitness scores and interactions with key active site amino acids are identified as potent chymase hits. Moreover, DFT study is performed which confirms very clear trends between electronic properties and inhibitory activity (IC(50)) data thus successfully validating "Hypo1" by DFT method. Therefore, this research exertion can be helpful in the development of new potent hits for chymase. In addition, the combinational use of docking, orbital energies and molecular electrostatic potential analysis is also demonstrated as a good endeavor to gain an insight into the interaction between chymase and inhibitors.
