https://www.selleckchem.com/products/BIRB-796-(Doramapimod).html Aminobenzosuberone-based PfA-M1 inhibitors were explored as novel antimalarial agents against two different Plasmodium falciparum strains. The 4-phenyl derivative 7c exhibited the most encouraging growth inhibitory activity with IC50 values of 6.5-11.2 µM. X-ray crystal structures and early assessment of DMPK/ADME-Tox parameters allowed us to initiate structure-based drug design approach and understand the liabilities (such as potential metabolic and aqueous solubility issues) as well as identify the opportunities for improvement of this aminobenzosuberone series. It also suggested that compound 7c should be regarded as an attractive chemical tool to investigate the different biological roles of this multifunctional PfA-M1 protein. Herein we report on a new series of hydrazidoureidobenzensulfonamides investigated as inhibitors of the cytosolic human (h) hCA I and II isoforms, as well as the transmembrane, tumor-associated enzymes hCA IX and XII. The reported derivatives contain a 4-substituted piperidine fragment in which the hydrazidoureido linker has been involved as spacer between the benzenesulfonamide fragment which binds the zinc ion from the active site, and the tail of the inhibitor. Depending on the substitution pattern at the piperidine ring, low nanomolar inhibitors were detected against hCA II, hCA IX and hCA XII, making the new class of sulfonamides of interest for various pharmacologic applications. Ten new bisbenzylisoquinoline alkaloids (1-10) and eight known analogues (11-18) were obtained from the roots of Stephania tetrandra. The structures of these compounds were determined by spectroscopic methods, single-crystal X-ray diffraction, electronic circular dichroism analyses, and chemical method. Compounds 1, 15, and 16 showed the better anti-inflammatory activities with IC50 values of 15.26 ± 2.99, 6.12 ± 0.25, and 5.92 ± 1.89 μM, respectively. Compound 18 possessed cytotoxic activitie
