Polyacetylated labdane-type diterpenoids, ptychantins P-R from Chinese liverwort Ptychanthus striatus.
Wu JY, Zhang JZ, Kang YQ, Wang X, Fan PH, Zhou JC, Lou HX. Wu JY, et al. J Asian Nat Prod Res. 2015 May;17(5):462-7. doi: 10.1080/10286020.2015.1011140. Epub 2015 Feb 13. J Asian Nat Prod Res. 2015. PMID: 25677361
Three new polyacetylated labdane diterpenoids ptychantins P-R (1-3) and four known compounds (4-7) were isolated from an EtOH extract of the Chinese liverwort Ptychanthus striatus (Lehm. & Lindenb.) Nees. Their structures were established by extensive analysis of spect …

Labeling patterns of chloroplastidic isoprenoids in cultured cells of liverwort Ptychanthus striatus.
Karunagoda RP, Itoh D, Katoh K, Nabeta K. Karunagoda RP, et al. Biosci Biotechnol Biochem. 2001 May;65(5):1076-81. doi: 10.1271/bbb.65.1076. Biosci Biotechnol Biochem. 2001. PMID: 11440120 Free article.
Incorporation studies administering 2H- and 13C-labeled mevalonate (MVA) and 13C-labeled glucose to suspension cultured cells of the liverwort, Ptychanthus striatus, were carried out in order to examine the biosynthesis of the phytyl side-chain of chlorophyll a. ...

Synthetic transformation of ptychantin into forskolin and 1,9-dideoxyforskolin.
Hagiwara H, Takeuchi F, Kudou M, Hoshi T, Suzuki T, Hashimoto T, Asakawa Y. Hagiwara H, et al. J Org Chem. 2006 Jun 9;71(12):4619-24. doi: 10.1021/jo060477e. J Org Chem. 2006. PMID: 16749796
Forskolin (1), a highly oxygenated labdane diterpenoid and an activator of adenylate cyclase, has been synthesized in 12 steps and 12% overall yield from ptychantin A (4), which has been isolated from liverwort Ptychanthus striatus in good yield. The 1alpha-hydroxy group w …
