The cysteine proteases, cruzain and TbrCATL (rhodesain), are therapeutic targets for Chagas disease and Human African Trypanosomiasis, respectively. Among the known inhibitors for these proteases, we have described N4-benzyl-N2-phenylquinazoline-2,4-diamine (compound 7 in the original publication, 1a in this study), as a competitive cruzain inhibitor (Ki = 1.4 μM). Here, we describe the synthesis and biological evaluation of 22 analogs of 1a, containing modifications in the quinazoline core, and in the substituents in positions 2 and 4 of this ring. The analogs demonstrate low micromolar inhibition of the target proteases and cidal activity against Trypanosoma cruzi with up to two log selectivity indices in counterscreens with myoblasts. Fourteen compounds were active against Trypanosoma brucei at low to mid micromolar concentrations. During the optimization of 1a, structure-based design and prediction of physicochemical properties were employed to maintain potency against the enzymes while removing colloidal aggregator characteristics observed for some molecules in this series.

HDAC and CDK inhibitors have been demonstrated to be synergistically in suppressing cancer cell proliferation and inducing apoptosis. In this work, we incorporated the pharmacophore groups of HDACs and CDKs inhibitors into one molecule to design and synthesize a series of purin derivatives as HDAC/CDK dual inhibitors. The lead compound 6d, showing good HDAC1 and CDK2 inhibitory activity with IC50 values of 5.8 and 56 nM, respectively, exhibited attractive potency against several cancer cell lines in vitro. This work may lead to the discovery of a novel scaffold and potential dual HDAC/CDK inhibitors.
SUBSTITUTED BICYCLIC PYRIMIDINE-BASED COMPOUNDS AND COMPOSITIONS AND USES THEREOF
-
Paragraph 00231; 00232, (2018/08/20)
Novel C-2-substituted bicyclic compounds of Formula I have been prepared and found to be useful as potent inhibitors of hGGPPS by inhibiting geranylgeranylation of proteins and inhibiting the biosynthesis of GGPP. The application is directed to these compounds, to compositions comprising these compounds, and to their use, in particular as medicaments for use in the treatment of cancer and other conditions which are treatable by inhibiting human geranylgeranylation pyrophosphate hGGPPS activity.
