Isolated Cembranoid Diterpenes From Sarcophyton tenuispiculatum and Semi‑Synthetic Derivatives with Pro‑Apoptotic Activity in Breast Cancer Cells.
Article in Chemistry & biodiversity, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The soft coral Sarcophyton tenuispiculatum was investigated for its secondary metabolites, leading to the isolation of four natural isolates, including 7α,8α-epoxy-1(15),3,11-cembratriene-16,2β-olide (1), 2β,16,7α,8α-diEpoxy-1(15),3,11-cembratriene (2), apo-9'-fucoxanthinone (3), and (+)-viridiflorol (4). Semi-synthetic modification of compound 1 produced five new cembranoids: epi-Trochelioid B (5), chlorobenzocembrin (6), benzocembrin (7), nitrobenzocembrin (8), and Trochelioid C (9). Structural elucidation was achieved using extensive spectroscopic analyses, including 1D/2D NMR and HR-ESI-MS. Biological evaluation demonstrated that chlorobenzocembrin (6) exhibited more cytotoxic activity against breast cancer cell lines MCF-7 and MDA-MB-231, inducing apoptosis through ROS accumulation and caspase-6 activation. Acute toxicity studies in mice revealed hepatotoxicity and nephrotoxicity in doses > 250 mg/kg. Preliminary antiproliferative SAR highlights that epoxide ring opening followed by aryl substitution at C‑7 on 7α,8α-epoxy-1(15),3,11-cembratriene-16,2β-olide enhanced cytotoxic activity and suggests that incorporating substituents associated with enhanced cytotoxic activity at the same position may represent a promising strategy for semi‑synthetic optimization of cembranoid scaffolds toward more potent and selective anticancer agents.
