Ecdysone analogs with various side chains at the 17-position of the steroid structure enhanced the incorporation of N-acetylglucosamine as 20-hydroxyecdysone into the cultured integument prepared from Chilo suppressalis. Their activity in terms of the concentration required to give 50% of the maximum response varied with the structure. Piperonyl butoxide,(More)
Dibenzoylhydrazines are the nonsteroidal ecdysone agonists. Using comparative molecular field analysis, we previously found that the alkyl side chain of 20-hydroxyecdysone (20E) is three-dimensionally superposable with one of their two aryl moieties. To identify the aryl moiety that is better superposable on the alkyl chain, we synthesized compounds in(More)
How the cultural history of Tokyo has developed since the early modern era (1600-1868) and continues to unfold in the twenty-first century, as seen from the standpoint of global and comparative religious and literary perspectives. ranked at the top of Japanese gardens outside of the native country. Participants will be exposed to many aspects of Japan's(More)
N-tert-Butyl-N,N'-dibenzoylhydrazines, agonists of 20-hydroxyecdysone, decelerated the rising and falling phases of an action potential, which had been electrically induced in the cockroach giant axon, at moderately high concentrations. 4-Aminopyridine, a blocker of potassium channels of nerve, selectively decelerated the falling phase of the action(More)
