Synthesis and in vitro activity of oleanane type derivatives against Chlamydia trachomatis

Özet

Modified synthesis of 3β-nicotinoyloxy-olean-12(13)-en-28-oic acid and 3-deoxy-3a-homo-3a-aza-28-hydroxy-olean-12(13)-enefrom natural occurring oleanolic acid is suggested. These compounds and two others of ursane and lupane typetriterpenoids(3-oximino-urs-12-en-28-oic acidand 3-deoxy-3a-homo-3a-aza-28-hydroxy-lup-12(13)-ene) were screened in vitroagainstChlamydia trachomatisstrain F-3271/Belarus/2015. Oleanane triterpenoids became the leading compounds with chemotherapeutic index > 8 and were chosen for further research.
