Marine Terpenic Endoperoxides. Mar Drugs 2021; 19:md19120661. [PMID: 34940660 PMCID: PMC8703521 DOI: 10.3390/md19120661] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2021] [Revised: 11/19/2021] [Accepted: 11/23/2021] [Indexed: 12/12/2022] Open
Abstract
Organic extracts of marine invertebrates, mainly sponges, from seas all over the world are well known for their high in vitro anticancer and antibiotic activities which make them promising sources of compounds with potential use as pharmaceutical leads. Most of the structures discovered so far have a peculiar structural feature in common: a 1,2-dioxane ring. This is a highly reactive heterocycle that can be considered as an endoperoxide function. Together with other structural features, this group could be responsible for the strong biological activities of the substances present in the extracts. Numerous research programs have focused on their structural elucidation and total synthesis since the seventies. As a consequence, the number of established chiral centres and the similarity between different naturally occurring substances is increasingly higher. Most of these compounds have a terpenoid nature, mainly diterpene and sesterterpene, with several peculiar structural features, such as the loss of one carbon atom. Although there are many reviews dealing with the occurrence of marine peroxides, their activities, or potential pharmaceutical uses, no one has focused on those having a terpene origin and the endoperoxide function. We present here a comprehensive review of these compounds paying special attention to their structural features and their biological activity.

Abstract
Four new pregnane steroids, 3β,4β,16β-trihydroxypregna-5,17-diene-10,2-carbolactone (1), 16β-acetoxy-3β,4β-dihydroxypregna-5,17-diene-10,2-carbolactone (2), 12β-acetoxy-3β,4β,16β-trihydroxypregna-5,17-diene-10,2-carbolactone (3), and 12β,16β-diacetoxy-3β,4β-dihydroxypregna-5,17-diene-10,2-carbolactone (4) were isolated from an extract of an Epipolasis sp. marine sponge. The structures of the new compounds were determined by extensive NMR spectroscopic analysis and comparison with data from previously reported compounds.

Abstract
A bioassay-guided fractionation yielded five new polycyclic phloroglucines derivatives, namely, gundlachiione A (1), gundlachiione B (2), gundlachiione C (3), gundlachiione D (4) and gundlachiione E (5) from the fruits of Clusia gundlachii, collected in Puerto Rico, USA. Their structures were determined by full spectroscopic data, including 2D NMR COSY, HMQC, HMBC, and NOESY experiments, and HRESIMS. Compounds 1 and 3 demonstrated activities against Leishmania donovani intracellular macrophage amastigotes in THP1 cultures, comparable to those observed for the standard drug pentamidine (IC50 and IC90 values 0.84 and 6.13 μg/mL, 2.32 and 3.01 μg/mL, 0.77 and 2.99 μg/mL, respectively). Both compounds, 1 and 3, also showed weak activities against L. donovani promastogotes and absence of cytotoxicity against transformed THP 1 cells.
