The invention relates to methods of treating or preventing malaria which comprises administering to a patient in need thereof, an effective amount of a 1H-indazole-3-carboxamide derivative of general formula (I), in the form of a base or of an addition salt with an acid, or in the form of a hydrate or of a solvate of said base or acid addition salt.
A non-selective inhibitor (1) of FMS-like tyrosine kinase-3 (FLT3) was identified by fragment screening and systematically modified to afford a potent and selective inhibitor 26. We confirmed that 26 inhibited the growth of FLT-3-activated human acute myeloid leukemia cell line MV4-11. Our design strategy enabled rapid development of a novel type of FLT3 inhibitor from the hit fragment in the absence of target-structural information. (C) 2016 Elsevier Ltd. All rights reserved.

We have designed and synthesized twenty-six N-arylindazole-3-carboxamide (3a-p) and N-benzoylindazole (6a-j) derivatives to discover with excellent inhibition activities of alpha-MSH-stimulated melanogenesis. In the bio evaluation studies of these compounds, we discovered eighteen compounds, out of twenty-six exhibited more potent inhibition than the positive control arbutin. From the SAR studies, we identified 3k and 6g as lead compounds which displayed almost 5 and 9 times more potent inhibition of alpha-MSH-stimulated melanogenesis respectively than the reference arbutin. It is also evident the presence of electron withdrawing group at para position (R-3) for the compounds (3a-p) and presence of +M group at ortho position (R-5) for the compounds (6a-j) were crucial for their excellent inhibition activities of alpha-MSH-stimulated melanogenesis.
