METHODS AND RESULTS:
The aerial parts of Peganum harmala L. (APP) is a well-known and effective herbal medicine in China, and has been commonly used for treating various ailments, including cough and asthma. OBJECTIVES: To evaluate the antitussive, expectorant, and bronchodilating effects of the quinazoline alkaloids (±)-vasicine (VAS), deoxyvasicine (DVAS) (both isolated from the alkaloid fraction of APP) and (±)-Vasicinone (VAO) (synthesized from VAS).
CONCLUSIONS:
Quinazoline alkaloids VAS, VAO, and DVAS have significant antitussive, expectorant, and bronchodilating activities. VAS, VAO, and DVAS are the active ingredients in APP, which can be used to treat respiratory disease. |

| Indian J Exp Biol. 2014 Jul;52(7):705-11. | | Evaluation of hepatoprotective activity of vasicinone in mice.[Pubmed: 25059038] | Justicia adhatoda (vasaka) leaves have long been used in Indian Ayurvedic system of medicine as antitussive. Its crude extract has been previously reported to have hepatoprotective activity.
METHODS AND RESULTS:
Vasicinone was isolated from leaves of J. adhatoda, column purified and characterized using, TLC UV, FT-IR and 1H NMR. The isolated vasicinone was evaluated for hepatoprotective activity using (CCl4)-induced acute hepatotoxicity model in mice. CCl4 treatments lead to significant increase in SGOT, SGPT, ALP levels. Pre-treatment with vasicinone and silymarin (25 mg/kg/day for 7 days) significantly decreased these enzyme levels. Histopathology of the livers from vasicinone and silymarin pre-treated animals showed normal hepatic cords and absence of necrotic changes suggesting pronounced recovery from CCl4 induced liver damage. Both vasicinone and silymarin significantly decrease the CCl4 mediated increase in pentobarbital indiced sleeping time in experimental animals, thus indicating recovery of liver function.
CONCLUSIONS:
Based on the above results it can be concluded that vasicinone may act as hepatoprotective in mice and warrants further investigation on human volunteers. |
