Limited therapeutic options are available for the treatment of human schistosomiasis caused by the parasitic Schistosoma flatworm. The B cell lymphoma-2 (BCL-2)-regulated apoptotic cell death pathway in schistosomes was recently characterized and shown to share similarities with the intrinsic apoptosis pathway in humans. Here, we exploit structural differences in the human and schistosome BCL-2 (sBCL-2) pro-survival proteins toward a novel treatment strategy for schistosomiasis. The benzothiazole hydrazone scaffold previously employed to target human BCL-XL was repurposed as a starting point to target sBCL-2. We utilized X-ray structural data to inform optimization and then applied a scaffold-hop strategy to identify the 5-carboxamide thiazole hydrazone scaffold (43) with potent sBCL-2 activity (IC50 30 nM). Human BCL-XL potency (IC50 13 nM) was inadvertently preserved during the optimization process. The lead analogues from this study exhibit on-target activity in model fibroblast cell lines dependent on either sBCL-2 or human BCL-XL for survival. Further optimization of the thiazole hydrazone class is required to exhibit activity in schistosomes and enhance the potential of this strategy for treating schistosomiasis.

Two series of compounds carrying 3-amino-1,2,4-triazole scaffold were synthesized and evaluated for their anticancer activity against a panel of cancer cell lines using XTT assay. The 1,2,4-triazole synthesis was revisited for the first series of pyridyl derivatives. The biological results revealed the efficiency of the 3-amino-1,2,4-triazole core that could not be replaced and a clear beneficial effect of a 3-bromophenylamino moiety in position 3 of the triazole for both series (compounds 2.6 and 4.6) on several cell lines tested. Moreover, our results point out an antiangiogenic activity of these compounds. Overall, the 5-aryl-3-phenylamino-1,2,4-triazole structure has promising dual anticancer activity.
