| | KS 505a Usage And Synthesis |
| Description | Longestin is a trypanocidal agent; isolated from Steptomyces argenteolus; inhibits brain calcium- and calmodulin-dependent cyclic nucleotide phosphodiesterase. | | Uses | Longestin (KS-505a) is a specific inhibitor of phosphodiesterase with antitrypanosomal activity, which is derived from Streptomyces argenteolus. Longestin is promising for research of anti-amnesia agent[1][2]. | | References | [1] Ozaki T, et al.
