Osteoarthritis (OA) is a degenerative disease characterized by joint destruction and loss of cartilage. There are many unmet needs in the treatment of OA and there are few promising candidates for disease-modifying OA drugs, particularly, anabolic agents. Here, we describe the identification of novel quinazolin-4(3H)-one derivatives, which stimulate chondrocyte cartilage matrix production via TRPV4 and mitigate damaged articular cartilage. We successfully identified the water-soluble, highly potent quinazolin-4(3H)-one derivative 36 and studied its intra-articular physicochemical profile to use in in vivo surgical OA model studies. Compound 36·HCl provided relief from OA damage in a rat medial meniscal tear (MT) model. Specifically, 36·HCl dose-dependently suppressed cartilage degradation and enhanced the messenger RNA expression of aggrecan and SOX9 in cartilage isolated from MT-operated rat knees compared with knees treated with vehicle. These results suggest that 36 induces anabolic changes in articular cartilage and consequently reduces OA progression.

A novel series of benzylidene-quinazolinone hybrids 8a,b and 10a-n were designed, synthesized, and evaluated for their in vitro α-glucosidase inhibitory effect aiming to discover efficient anti-diabetic agents. The synthesized compounds were assessed for their in vivo anti-hyperglycemic activities against STZ-induced hyperglycemic rats. Five compounds (10m, 10f, 10c, 10d and 8b) demonstrated potent activities with percent reduction in blood glucose levels of 43.07, 40.14, 39.83, 37.04 and 36.16, respectively. The most active members were further evaluated in vitro for their α-glucosidase inhibitory binding affinities. Among them, Compound 10m containing 4-hydroxybenzylidene moiety and compound 10f with 4-chlorobenzylidene moiety connected to the acetohydrazide demonstrated the most potent inhibitory activities towards α-glucosidase with IC50 values of 561 and 610 μM, respectively. Molecular docking study was performed in order to understand the molecular interactions between the molecule and enzyme.

In the present study, a series of novel quinazolinone hybrids, viz. triazepino-quinazolinones 4, thiazolo-triazolo-quinazolinones 7 and triazolo-quinazolinones 8 have been synthesized from the key intermediate 3-(substituted phenyl)-2-hydrazinoquinazolin-4(3H)-ones 3. All the newly synthesized compounds were characterized by means of spectral (IR, 1H NMR, 13C NMR) and elemental analysis. The target compounds were biologically screened for their in vitro antimicrobial and antitubercular activities against pathogenic strain. The results of bioassay demonstrated that some of the compounds exhibited pronounced antimicrobial activity comparable to that of standard drugs tested under similar conditions. Compounds 4c, 4e, 7e and 8b showed relatively very good inhibitory activity against pathogenic bacteria with minimum inhibitory concentration (MIC) of 2.6 μg/mL, 5.2 μg/mL, while the rest of the compounds showed moderate activity. Compounds 4c and 8b were found to be nearly equipotent with ciprofloxacin against P. aeruginosa with MIC 5.2 μg/mL, while compound 8b was more potent against pathogenic bacteria S. aureus. It is very remarkable that four compounds, 4c, 4e, 7e and 8b showed pronounced antifungal activity against selected pathogenic fungi, A. niger, C. albicans with MIC 2.6 μg/mL and 5.2 μg/mL. The antitubercular activity of synthesized compounds reveal that compound 8b showed better activity than the other compounds with a MIC of 5.2 μg/mL against M. tuberculosis (H37Rv). Molecular docking studies of the compounds were performed to rationalize the inhibitory properties of these compounds and results showed that these compounds have good binding energy and better binding affinity within the active pocket, thus these compounds may be considered as potent inhibitors towards selective targets.

A series of new quinazolinone-dihydropyrano[3,2-b]pyran derivatives 10A-L were synthesized by simple chemical reactions and were investigated for inhibitory activities against α-glucosidase and α-amylase. New synthesized compounds showed high α-glucosidase inhibition effects in comparison to the standard drug acarbose and were inactive against α-amylase. Among them, the most potent compound was compound 10L (IC50 value = 40.1 ± 0.6 μM) with inhibitory activity around 18.75-fold more than acarboase (IC50 value = 750.0 ± 12.5 μM). This compound was a competitive inhibitor into α-glucosidase. Our obtained experimental results were confirmed by docking studies. Furthermore, the cytotoxicity of the most potent compounds 10L, 10G, and 10N against normal fibroblast cells and in silico druglikeness, ADME, and toxicity prediction of these compounds were also evaluated.
