Design and Synthesis of Dual-Target Inhibitors Targeting Androgen Receptors and Glucocorticoid Receptors to Overcome Antiandrogen Resistance in Castration-Resistant Prostate Cancer
Androgenreceptor (AR) antagonists play important roles in the treatment of castration-resistantprostatecancer (CRPC). The glucocorticoidreceptor (GR) upregulation leads to drug resistance for clinically used antiandrogens. Therefore, blocking AR/GR signaling simultaneously has become an efficient strategy to overcome the drug resistance of CRPC. Our previous work indicated that Z19 could inhibit
and σ2 receptors of a series of new piperidine-4-carboxamide derivatives variously substituted on the amide nitrogen atom. Specifically, we assessed the effects exerted on σ receptor affinity by substituting the N-benzylcarboxamide group present on a series of compounds previously synthesized in our laboratory with different cyclic or linear moieties. The synthesized compounds 2a–o were tested to estimate

report an exploration of the antimalarial compound MMV692140. The mode of resistance was identified as PfeEF2. The structural motif was explored in a chemistry program, resulting in the identification of MMV1919557, an analog with significantly improved antimalarial potency. This new series could provide a tool to further understand the potential of PfeEF2 as a target for malaria treatment.
