Five novel highly oxygenated diterpenes of Orthosiphon stamineus from Myanmar.[Pubmed:11374950]
J Nat Prod. 2001 May;64(5):592-6.
Five novel highly oxygenated diterpenes, orthosiphols K (1), L (2), M (3), and N (4) and norstaminone A (5), were isolated from the aerial part of Orthosiphon stamineus, together with three known diterpenes, orthosiphols A (6) and B (7) and Neoorthosiphol A (8). Orthosiphol L (2) is an isopimarane-type diterpene with a hydroxyl group at C-12, which supports the biogenesis of staminane-type diterpenes, i.e., migration of a vinylic group from C-13 of isopimarane to C-12. Norstaminone A (5) has a staminane carbon framework and supports the biosynthetic pathway from staminols to norstaminols via staminolactones. All the isolated compounds showed mild to weak antiproliferative activities toward highly liver metastatic colon 26-L5 carcinoma and human HT-1080 fibrosarcoma cell lines.
[Antihypertensive substance in the leaves of kumis kucing (Orthosiphon aristatus) in Java Island].[Pubmed:10825811]
Yakugaku Zasshi. 2000 May;120(5):474-82.
The water decoction of leaves of kumis kucing, Orthosiphon aristatus (BL.) MIQ (Lamiaceae) which has been prescribed in Javanese traditional medicine (jamu) for the treatment of hypertension etc., was partitioned into a mixture of chloroform and water. The chloroform-soluble portion showed an inhibitory effect on the contractile responses on rat thoracic aorta smooth muscle stimulated with KCl beforehand, while the water-soluble portion showed no effect. The chloroform-soluble portion was separated to afford a new benzochromene [orthochromene A (7)], two new isopimarane-type diterpenes [orthosiphonone A (10), orthosiphonone B (11)], and two novel migrated pimarane-type diterpenes [Neoorthosiphol A (12), neoorthosiphol B (13)], together with eight known compounds (1-6, 8, 9). Among those thirteen substances, it was found that a major constituent in the water decoction of leaves, methylripariochromene A (5), exhibited a continuous decrease in systolic blood pressure after subcutaneous administration in conscious stroke-prone spontaneously hypertensive rats (SHRSP).
