|A natural small molecule voacangine inhibits angiogenesis both in vitro and in vivo.[Pubmed: 22155252]|
|Angiogenesis, the formation of new blood vessels from pre-existing ones, plays a critical role in normal and pathological phenotypes, including solid tumor growth and metastasis.
Accordingly, the development of new anti-angiogenic agents is considered an efficient strategy for the treatment of cancer and other human diseases linked with angiogenesis.
METHODS AND RESULTS:
We have identified Voacangine, isolated from Voacanga africana, as a novel anti-angiogenic agent. Voacangine inhibits the proliferation of HUVECs at an IC(50) of 18 μM with no cytotoxic effects. Voacangine significantly suppressed in vitro angiogenesis, such as VEGF-induced tube formation and chemoinvasion. Moreover, the compound inhibits in vivo angiogenesis in the chorioallantoic membrane at non-toxic doses. In addition, Voacangine decreased the expression levels of hypoxia inducible factor-1α and its target gene, VEGF, in a dose-dependent manner.
Taken together, these results suggest that the naturally occurring compound, Voacangine, is a novel anti-angiogenic compound.

|Activation and inhibition of thermosensitive TRP channels by voacangine, an alkaloid present in Voacanga africana, an African tree.[Pubmed: 24484240]|
|Voacangine (1) is an alkaloid found in the root bark of Voacanga africana.
Our previous work has suggested that 1 is a novel transient receptor potential vanilloid type 1 (TRPV1) antagonist.
METHODS AND RESULTS:
In this study, the agonist and antagonist activities of 1 were examined against thermosensitive TRP channels. Channel activity was evaluated mainly using TRP channel-expressing HEK cells and calcium imaging. Herein, it was shown that 1 acts as an antagonist for TRPV1 and TRPM8 but as an agonist for TRPA1 (EC50, 8 μM). The compound competitively blocked capsaicin binding to TRPV1 (IC50, 50 μM). Voacangine (1) competitively inhibited the binding of menthol to TRPM8 (IC50, 9 μM), but it showed noncompetitive inhibition against icilin (IC50, 7 μM). Moreover, the compound selectively abrogated chemical agonist-induced TRPM8 activation and did not affect cold-induced activation.
Among these effects, the TRPM8 inhibition profile is unique and noteworthy, because to date no studies have reported a menthol competitive inhibitor of TRPM8 derived from a natural source. Furthermore, this is the first report of a stimulus-selective TRPM8 antagonist. Accordingly, 1 may contribute to the development of a novel class of stimulus-selective TRPM8 blockers.
