Indole-Diterpenoids with Protein Tyrosine Phosphatase Inhibitory Activities from the Marine-Derived Fungus Penicillium sp. KFD28

Abstract: Five new indole-terpenoids named penerpenes E−I (1−5), along with seven known ones (6−12), were isolated from the marine-derived fungus Penicillium sp. KFD28 from a bivalve mollusk, Meretrix lusoria. The structures of the new compounds were elucidated from spectroscopic data and ECD spectroscopic analyses. Compound 1 was assigned as an indole-diterpenoid with a unique 6/5/5/ 6/6/5/5 heptacyclic ring system. Compound 2 represents an indole-diterpenoid with a new carbon skeleton derived from paxilline by the los… Show more

“…KFD28, which is associated with the bivalve mollusk, Meretrix lusoria (Haikou Bay, China), nine new diverse skeletons of indole terpenoids, penerpenes A−D (437-440) [146] and E-I (441-445) [147], and nine known indole terpenoids, including paxilline, emindole SB, and 7-hydroxypaxilline-13-ene, were isolated. Notably, compound 437 possesses a 1,4-dihydro-2Hbenzo[d] [1,3] oxazine moiety in an unusual spiro indole diterpene; compound 438 has an uncommon heptacyclic scaffold containing pyridine in the indole diterpene; compounds 439, 440, and 442 are norindole diterpenoids with new carbon frameworks possibly derived from paxilline via the loss of 3-5 carbons; compound 441 bears a unique 6/5/5/6/6/5/5 heptacyclic ring system; and compound 443 contains an unusual 6/5/5/6/6/7 hexacyclic motif bearing a 1,3-dioxepane ring rarely found in nature [146,147]. Compounds 437 and 438 and emindole SB are considered to be new potent protein tyrosine phosphatase (PTP1B and TCPTP, IC 50 = 0.7-5.0 µM) inhibitors via PTP inhibition and molecular docking experiments [146].…”

“…Compounds 441, 442, 444, and 7-hydroxypaxilline-13-ene inhibited PTP1B (IC 50 = 13-27 µM). Compound 441 also showed anti-PTPσ activity (IC 50 = 38 µM), while compound 444 and 7-hydroxypaxilline-13-ene inhibited TCPTP (IC 50 = 35 and 37 µM, respectively) [147]. Penicindopene A (446), possessing a 3-hydroxyl-2-indolone moiety rarely found in indole diterpenes, was isolated from the deep-sea fungus Penicillium sp.…”
