Originating from the basic chalcone structure, bis-chalcones are characterized by their dual ,-unsaturated carbonyl systems and carry a range of biological activities that include antimicrobial, antiviral, antiparasitic, antioxidant, antiproliferative, and chemical reactivities that warrant a review to cover recent progress. Thus, this review presents the significant potential demonstrated by bis-chalcones in various biological applications. For example, compounds showed excellent antiparasitic activity against leishmania with good selectivity index, and compounds - showed submicromolar activity against SupT1 cells. Compound stood out in its antiproliferative activity against a panel of 60 different cell lines. Compounds and have been shown as submicromolar noncompetitive xanthine oxidase inhibitors. We also present their recent applications in material science, for example, as photosensitizers and photoinitiators, to showcase their broader potential for innovation in both medicinal chemistry and industrial applications.

The synthesis of ()-1-(1,3-diphenylallyl)-1-1,2,4-triazoles and related compounds as anti-mitotic agents with activity in breast cancer was investigated. These compounds were designed as hybrids of the microtubule-targeting chalcones, indanones, and the aromatase inhibitor letrozole. : A panel of 29 compounds was synthesized and examined by a preliminary screening in estrogen receptor (ER) and progesterone receptor (PR)-positive MCF-7 breast cancer cells together with cell cycle analysis and tubulin polymerization inhibition.

Novel 1,2,3-triazole hybrids bearing various substituents have been synthesized as potential anticancer agents. Ligand-based approach has been adopted to design these compounds relying on the hybridization of 1,2,3-triazole with α,β-unsaturated carbonyl, 5- and 6-membered heterocyclic scaffolds. All synthesized members were investigated for their cytotoxic potency against nine types comprising 60 panels of human cancerous cells by the US National Cancer Institute: Development Therapeutic Program (US_NCI_DTP).

Current strategies centred on either merging or linking initial hits from fragment-based drug design (FBDD) crystallographic screens generally do not fully leaverage 3D structural information. We show that an algorithmic approach (Fragmenstein) that 'stitches' the ligand atoms from this structural information together can provide more accurate and reliable predictions for protein-ligand complex conformation than general methods such as pharmacophore-constrained docking. This approach works under the assumption of conserved binding: when a larger molecule is designed containing the initial fragment hit, the common substructure between the two will adopt the same binding mode.

Epidermal growth factor receptor (EGFR) is amongst the earliest targeted kinases by small-molecule inhibitors for the management of EGFR-positive cancer types. While a few inhibitors are granted FDA approval for clinical use, discovery of new inhibitors is still of merit to enhance ligand-binding stability and subsequent enzyme inhibition. Thus, a structure-based design approach was adopted to devise a new series of twenty-nine N3-substituted quinazolin-4-ones as type I ATP-competitive inhibitors targeting the deep hydrophobic pocket of EGFR.

Respiratory syncytial virus (RSV) is the leading cause of acute lower respiratory infections in babies across the world. Irrespective of progress in the development of RSV vaccines, effective small molecule drugs are still not available on the market. Based on our previous data we designed and synthesized triazole-linked coumarin-monoterpene hybrids and showed that they are indeed effective in inhibiting the RSV replication.
