Abstract: The invention provides novel diamino-functionalized chalcone derivatives and analogues thereof. Use of the compounds, or compositions comprising them, as pharmaceutically active agents, in particular against bacterial and parasitic infections, is also disclosed. The invention further relates to a method for detecting inhibitory effects against e.g., bacteria, parasites, fungi, and helminths. The chalcones of the invention carry amino substituents and exhibit enhanced biological effects combined with improved metabolic and physicochemical properties, making the compounds useful as drug substances, in particular as antiparasitic and bacteriostatic agents.

Abstract: The invention provides novel alkoxyaminochalcone derivatives and analogues thereof. Use of the compounds, or compositions comprising them, as pharmaceutically active agents, in particular against bacterial and parasitic infections, is also disclosed. The invention further relates to a method for detecting inhibitory effects against e.g., bacteria, parasites, fungi, and helminths. The chalcones of the invention carry amino substituents and exhibit enhanced biological effects combined with improved metabolic and physicochemical properties, making the compounds useful as drug substances, in particular as antiparasitic, bacteriostatic, and bacteriocidal agents.

Abstract: The present invention provides novel quaternary amino-functional chalcone derivatives and analogues exhibiting interesting antibacterial activity. The compounds have the general formula (Y1)m—Ar1(X1)—C(=O)VAr2(X2)?(Y2)p (I), wherein V designates —CH2—CH2—, —CH?CH— or —C?C—; Ar1 and Ar2 independently are aryl and heteroaryl; m=0, 1, 2, p=0, 1, 2, m+p>0; each Y1 and Y2 independently is -Z—N+(R1)(R2)R4 Q? (A); —NR3-Z—N+(R1)(R2)R4 Q? (B), or —O-Z—N+(R1)(R2)R4 Q? (C), R1, R2, R3, R4, X1, X2 are substituents, and Q? is an anion. The present invention also relates to the compounds for use as pharmaceutically active agents, in particular against bacterial infections (such as Gram-negative and Gram-positive bacteria, including antibiotic-sensitive or resistant strains), and in the medical treatment of bacterial infections in mammals.
