Evaluation of antibacterial, cytotoxicity, and apoptosis activity of novel chromene-sulfonamide hybrids synthesized under solvent-free conditions and 3D-QSAR modeling studies.

In this study, eleven novel chromene sulfonamide hybrids were synthesized by a convenient method in accordance with green chemistry. At first, chromene derivatives (1-9a) were prepared through the multi-component reaction between aryl aldehydes, malononitrile, and 3-aminophenol. Then, synthesized chromenes were reacted with appropriate sulfonyl chlorides by grinding method to give the corresponding chromene sulfonamide hybrids (1-11b).

Recent Advances in Biological Active Sulfonamide based Hybrid Compounds Part C: Multicomponent Sulfonamide Hybrids.

Sulfonamides, with the general formula R-SONRR, have attracted great attention since the early discovery of sulfonamide-containing antibacterial drugs. The combinations of certain sulfonamides and other drug molecules to form sulfonamide hybrids are being used to develop novel formulations with greater effectiveness and in a huge range of therapeutic applications such as antimicrobial, antifungal, anti-inflammatory, antitubercular, antiviral, antidiabetic, antiproliferative, carbonic anhydrase inhibitor, antimalarial, anticancer and other medicinal agents. Part C of this review presents recent advances in designing and developing multicomponent sulfonamide hybrids containing more than one biologically active heterocycle, such as coumarin, indole, pyridine, pyrimidine, pyrazole, triazole, oxazole, oxadiazole, triazine, quinazoline, and thiadiazol.

Recent Advances in Biological Active Sulfonamide based Hybrid Compounds Part B: Two-Component Sulfonamide Hybrids.

Sulfonamide compounds, also known as sulfa drugs, are a significant class of synthetic bacteriostatic antimicrobials and were the primary source of therapy against bacterial infections before the introduction of penicillin in 1941. Hybridization of sulfonamides with various pharmaceutically active heterocyclic moieties leads to sulfonamide hybrids with a wide variety of biological activities. Part B of this review presents the most recent advances in designing and developing more two-component sulfonamide hybrids containing triazole, thiadiazole, triazine, oxazole/ benzoxazole, isoxazole, oxadiazole, imidazole, benzimidazole, furan, benzofuran, thiophene, pyrrole, indazole, tetrazole, chromene/ chromone, pyridazine, quinoxaline, acridine, phthalazine, and xanthone between 2015 and 2020.

Recent Advances in Biological Active Sulfonamide based Hybrid Compounds Part A: Two-Component Sulfonamide Hybrids.

Sulfonamides constitute an important class of drugs, with many types of pharmacological agents possessing antibacterial, anti-carbonic anhydrase, anti-obesity, diuretic, hypoglycemic, antithyroid, antitumor, and anti-neuropathic pain activities. The sulfonamides are the compounds that have general formula R-SO2NHR', where the functional group is bound to aromatic, heterocycle, and aliphatic groups. The nature of the R and R' moiety is variable, starting with hydrogen and ranging to a variety of moieties incorporating organic compounds such as coumarin, isoxazole, tetrazole, pyrazole, pyrrole, and so many other pharmaceutical active scaffolds that lead to a considerable range of hybrids named as sulfonamide hybrids.
