Biological Activities
Compounds
Mandevilla illustris contains several specific pregnane compounds isolated from its rhizomes that exhibit varying pharmacological activities. Among these, compounds MI-15, MI-18, and MI-21 demonstrate the ability to displace concentration-response curves in isolated rat uteri. Specifically, MI-15 and MI-18 cause a parallel rightward displacement, while MI-21 also reduces the maximal response during these contractions. In contrast, the plant also contains MI-25 and MI-27, which appear to have little to no effect against bradykinin and acetylcholine responses. These findings highlight the diverse biological potential of the chemical constituents found within this plant species.
Conditions
Mandevilla illustris contains pregnane compounds from its rhizomes that effectively antagonize contractions induced by various substances in the rat isolated uterus. Specifically, these compounds treat Lysyl-bradykinin (L-BK) by causing a concentration-dependent displacement of its concentration-response curves. The plant also treats bradykinin (BK) through similar inhibitory actions that can reduce maximal responses. Furthermore, Mandevilla illustris treats acetylcholine (ACh) by markedly interfering with its sensitivity and maximal response levels. Finally, the plant's purified compounds treat oxytocin (Ot) by impacting the contractions it induces in the uterine preparation.
Preparations
Mandevilla illustris is prepared as rhizomes to facilitate the isolation of specific pregnane compounds. These biological components are extracted directly from the plant's rhizome structure for pharmacological study. Researchers utilized these rhizome-derived substances to examine their effects on uterine contractions in rat models. The study specifically focused on how compounds purified from the rhizome interfere with kinin and oxytocic actions. Consequently, the rhizome serves as the essential source material for testing the medicinal properties of Mandevilla illustris.
Parts used
Mandevilla illustris contains specific bioactive elements that can be extracted directly from its rhizome. Research has focused on isolating various pregnane compounds from this part of the plant to study their physiological effects. These isolated compounds have demonstrated a significant ability to influence uterine contractions in laboratory models. Specifically, the substances derived from the rhizome act against contractions induced by kinins, acetylcholine, and oxytocin. This highlights the medicinal potential of the plant's underground structures in managing smooth muscle activity.
