[PMID: 37175073 PMCID: PMC10180120 DOI: 10.3390/molecules28093663] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2023] [Revised: 04/11/2023] [Accepted: 04/17/2023] [Indexed: 05/15/2023] Open
Abstract
A sulfonated poly-4-vinyl pyridinium (PVPy-IL-B-SO3H) containing an acidic pyridinium/HSO3- ionic liquid moiety was prepared and used as a catalyst for the three-component reaction of malononitrile with 1-alkylindoline-2,3-diones and 1,3-dimethylpyrimidine-2,4,6(1H,3H,5H)-trione or methyl 5-hydroxy-1H-pyrazole-3-carboxylate, leading to methyl 6'-amino-5'-cyano-2-oxo-2'H-spiro[indoline-3,4'-pyrano[2,3-c]pyrazole]-3'-carboxylates or -3,4'-pyrano[2,3-d]pyrimidine]-6'-carbonitrile derivatives under ultrasonic irradiation conditions. The solid catalyst allows easy separation, is cheap, produces high yields under mild conditions, and does not require column chromatography for product isolation and purification.

Abstract
The pyranopyrimidine core is a key precursor for medicinal and pharmaceutical industries due to its broader synthetic applications as well as its bioavailability. Among its four possible isomers, we found that 5H-pyrano[2,3-d]pyrimidine scaffolds have a wide range of applicability, and in recent years, they have been intensively investigated, but the development of the main core is found to be more challenging due to its structural existence. In this review article, we cover all of the synthetic pathways that are employed for the development of substituted 4-aryl-octahydropyrano/hexahydrofuro[2,3-d]pyrimidin-2-one (thiones) and 5-aryl-substituted pyrano[2,3-d]pyrimidindione (2-thiones) derivatives through a one-pot multicomponent reaction using diversified hybrid catalysts such as organocatalysts, metal catalysts, ionic liquid catalysts, nanocatalysts, green solvents, catalyst-/solvent-free conditions, and miscellaneous catalysts as well as the mechanism and recyclability of the catalysts. This review mainly focuses on the application of hybrid catalysts (from 1992 to 2022) for the synthesis of 5H-pyrano[2,3-d]pyrimidine scaffolds. This review will definitely attract the world's leading researchers to utilize broader catalytic applications for the development of lead molecules.

Abstract
Cancer as one of the biggest human health problems remains unsolved. The identification of novel platforms with the highest efficacy and low toxicity is a big challenge among interested researchers. In this regard, we are interested to synthesis and evaluate antitumor activity of spiro[indolo[2,1-b]quinazoline-pyrano[2,3-d]pyrimidine] and spiro[indolo[2,1-b]quinazoline-pyrido[2,3-d]pyrimidine] derivatives. The spiro heterocycles were synthesized via four-component reaction of isatoic anhydride, isatins, malononitrile, and some CH-acids including barbituric acid/thiobarbituric acid and 4(6)-aminouracil in CH2Cl2 under reflux condition. The significant features of this process are short reaction time, easy purification without chromatographic process, and high yields which make it attractive. Next, we employed 2D and 3D cell culture models to evaluate biological activity of our compounds. Our results showed that among our seven products (4a-g), the compounds 4a and 4e are the best with 50% growth inhibitory concentration (IC50) value lower than etoposide. Our results support this idea that the compounds 4a and 4e may be potential for drug designing in cancer therapy. However, more experiments will be required to find possible side effects of related compounds in vivo.

Abstract
An important issue to discover biological structures is the design of sustainable, safe, clean, cost-effective, excellent efficient synthetic reactions, and minimal energy consumption to provide structural diversity compounds with interesting biological properties. Among five-membered nitrogen-containing heterocyclic compounds, indole-containing scaffolds are heterocyclic structures found in abundance in natural products and various synthetic compounds, which have received remarkable attention in recent years due to their therapeutic and pharmaceutical properties and valuable role in the process of drug discovery. Indoles can be synthesized by various procedures although most of these procedures have their own restrictions and drawbacks such as performing the reaction in a toxic solvent, need of transition-metal catalysts, and amount of waste solvents. Due to the medicinal importance of indole and the need for green methods of drug synthesis, this review highlights the latest green synthetic methods leading to the formation of indole-containing compounds focusing on the past 4 years with typical examples. This review is divided into two sections: green solvents and green techniques that lead to the synthesis of indole-derived scaffolds.

Abstract
Spiroindole and spirooxindole scaffolds are very important spiro-heterocyclic compounds in drug design processes. Significant attention has been directed at obtaining molecules based on spiroindole and spirooxindole derivatives that have bioactivity against cancer cells, microbes, and different types of disease affecting the human body. Due to their inherent three-dimensional nature and ability to project functionalities in all three dimensions, they have become biological targets. Considering reports on spiroindole and spirooxindole-containing scaffolds in the past decades, introducing novel synthetic procedures has been an active research field of organic chemistry for well over a century and will be useful in creating new therapeutic agents. This review summarizes the pharmacological significance of spiroindole and spirooxindole scaffolds and highlights the latest strategies for their synthesis, focusing particularly on the past 2 years with typical examples. The spiroindole and spirooxindoles in this review are divided by the type and ring size of the spirocycle that is fused to indole or oxindole. Summarizing these procedures will be very beneficial for discovering novel therapeutic candidate molecules.
