Mitraphylline 是一种绒毛钩藤中主要的五环吲哚类生物碱，可阻碍脂多糖介导的原代人中性粒细胞活化。

Mitraphylline has antiproliferative effects on human glioma and neuroblastoma cell lines. It also has anti-inflammatory activity, it inhibits lipopolysaccharide-mediated activation of primary human neutrophils.

The alkaloids of Uncaria tomentosa micropropagated plantlets and root cultures were isolated and identified by NMR and mass spectrometry. Plantlets yielded pteropodine (1), isopteropodine (2), Mitraphylline (3), isoMitraphylline (4), uncarine F (5), speciophylline (6), rhynchophylline (7) and isorhynchophylline (8). In plantlets growing under continuous light, tetracyclic alkaloids 7 and 8 decreased from 20 ± 1.8 at 2 months to 2.2 ± 0.33 mg/g dry wt at 6 months, while the pentacyclic alkaloids 1-4 increased from 7.7 ± 1.4 to 15 ± 0.05 mg/g dry wt, supporting their biogenetic conversion. Micropropagated plantlets produced four times more alkaloids (27.6 ± 3.1 mg/g dry wt) than greenhouse plants.
