Rational drug design of benzothiazole-based derivatives as potent signal transducer and activator of transcription 3 (STAT3) signaling pathway inhibitors
The cumulative evidence supports STAT3, a transcriptional mediator of oncogenic signaling, as a therapeutic target in cancer. The development of STAT3inhibitors remain an active area of research as no inhibitors have yet to be approved for cancer treatment. In a continuing effort to develop more potent STAT3inhibitors based on our previously identified hit compound 16w, a series of benzothiazole
A simple and efficient one-step procedure is described for the synthesis of a number of symmetrical 1,4-disubstituted piperazine-2,5-diones under phasetransfer conditions. The reactions are carried out at room temperature, starting from a suitable N-chloroacetamide in the presence of an aqueous solution of sodium hydroxide. Piperazine-2,5-diones were obtained with excellent selectivity in yields of
