Lignin from the Chinese quince (Chaenomeles sinensis) fruit offers a promising source of natural antioxidant for industrial applications. However, the utilization of Chinese quince fruit lignin is restricted by its inhomogeneous nature. Accordingly, Chinese quince fruit lignin was sequentially fractionated with organic solvents of increasing dissolving capacity to prepare homogeneous lignin fractions. The GPC (gel permeation chromatography) results showed that the molecular weights of lignin fractions increased from dichloromethane fraction to dioxane/water fraction. The five lignin fractions were also compared with respect to yield, carbohydrate content, thermal stability, inter-unit linkages, S/G ratios, and phenolic OH content. Among the five fractions, the ethyl acetate fraction showed a lower proportion of p-o-tv linkages (48.4%), the highest thermal stability, the highest phenolic OH content (2.8 mmol/g), and the highest DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging index and reducing power. The high antioxidant performance of the ethyl acetate fraction implies that it can be used as a natural antioxidant. This study shows that sequential solvent fractionation of lignin can produce homogeneous fractions with enhanced antioxidant performance. In addition, it demonstrates that Chinese quince fruits are a potentially valuable natural resource.

The Pot, Atom, and Step Economy (PASE) approach is based on the Pot economy principle and unites it with the Atom and Step Economy strategies; it ensures high efficiency, simplicity and low waste formation. The PASE approach is widely used in multicomponent chemistry. This approach was adopted for the synthesis of previously unknown hydroxyquinolinone substituted chromeno[2,3-b]pyridines via reaction of salicylaldehydes, malononitrile dimer and hydroxyquinolinone. It was shown that an ethanol-pyridine combination is more beneficial than other inorganic or organic catalysts. Quantum chemical studies showed that chromeno[2,3-b]pyridines has potential for corrosion inhibition. Real time H-1 NMR monitoring was used for the investigation of reaction mechanism and 2-((2H-chromen-3-yl)methylene)malononitrile was defined as a key intermediate in the reaction.

Background: The quinoline scaffold has been an attraction due to its pharmacological activities such as anti-HIV, anti-neoplastic, anti-asthmatic, anti-tuberculotic, anti-fungal, and anti-bacterial. Objective: The designed quinoline-3-carboxylate derivatives were synthesized through a two-step reaction and evaluated for antiproliferative activity against MCF-7 and K562 cell lines. Methods: Synthesized compounds were characterized by modern analytical techniques like NMR, 2DNMR, mass. and IR. Moreover, the purity of compounds was analyzed through the HPLC. In the progress of biological results, all synthesized compounds were evaluated for antiproliferative activity against MCF-7 and 1562 cell lines. Results: The synthesized compounds exhibited micromolar inhibition in all over the ranges, however, some of the compounds showed better activity than the standard anticancer drug such, as 4m and 4n with the IC50 value of 0.33 mu M against the MCF-7 cell line, and the compounds 4k and 4m showed potential activity against the K562 cell line with the IC50 value of 0.28 mu M. The anti-cancer activities of compounds were found to be thmugh the up-regulation of intrinsic apoptosis pathways. Conclusion: The biological data of all compounds in both cell lines were utilized for the structural activity relationship of the quinoline-3-carboxylate pharmacophore. The active lead was further validated through rigorous in silico studies for the drug-likeness (QED) and Absorption, Distribution, Metabolism, Excretion, and Toxicity (ADMET) properties. Here in the present research is utilized for the demonstration of an important pharmacophore, which could be utilized for further development to become a lead as an anticancer agent with minimal toxicity.

Reported is the enantioselective total syntheses of mavacuran alkaloids, (+)- taberdivarine H, (+)- 16- hydroxymethyl- pleiocarpamine, and (+)- 16- epi- pleiocarpamine, and their postulated biosynthetic precursor 16- formyl- pleiocarpamine. This family of monoterpene indole alkaloids is a target of choice since some of its members are subunits of intricate bisindole alkaloids such as bipleiophylline. Inspired by the biosynthetic hypothesis, an oxidative coupling approach from the geissoschizine framework to form the N1 @ C16 bond was explored. Quaternization of the aliphatic nitrogen center was key to achieving the oxidative coupling induced by KHMDS/ I2 as it masks the nucleophilicity of the aliphatic nitrogen center and locks in the required cis conformation.

A novel mesoporous composite was prepared through the hybridization of cobalt-based metal-organic framework (Co-MOF) and covalent organic framework (COF) based on melamine and terephthaldehyde (Co-MOF/COF) and characterized by FT-IR, SEM, XRD, EDS, BET, and STA analyses. The resultant composite was utilized as a robust recoverable catalyst in the condensation of several aldehydes with malononitrile to produce benzylidenemalononitrile derivatives in 62-94% yields under solvent-free conditions at room temperature using 15 mg of the catalyst and 5-60 min of reaction. The examination of catalytic performance of designated Co-MOF/COF exhibited an outstanding activity for the Knoevenagel condensation in a very short time. The recoverability, reusability and durability of Co-MOF/COF have also been investigated under applied conditions.

Carbazole alkaloids is an important class of natural products with diverse biological functions. So, the aim of this article is to explore new chemical entities containing carbazole scaffold as potential novel cytotoxic agents based on our developed three-component indole-to-carbazole reaction. Two series of carbazole derivatives were designed and synthesized, and their in vitro cytotoxic activities against three cell lines (A875, HepG2, and MARC145) were evaluated. The results indicated that some of these carbazole derivatives exhibited significantly good cytotoxic activities against tested cell lines compared with the control 5-fluorouracil (5-FU). Especially, carbazole acylhydrazone compounds 7g and 7p displayed high inhibitory activity on cancer cells, but almost no activity on normal cells. Further analysis of induced apoptosis for potential compounds indicated that the potential antitumor agents induced cell death in A875 cells at least partly (initially) by apoptosis, which might be used as promising lead scaffold for discovery of novel carbazole-type cytotoxic agents.
