Adhatoda vasica

The alkaloid vasicine was first isolated from Adhatoda vasica in 1925 but the structure (996) was elucidated only after a great amount of work, culminating in two independent syntheses in 1935 (B-53MI21301). It was made subsequently by a simple route from 2-aminobenzaldehyde and 4-amino-2-hydroxybutyraldehyde (994) followed by dehydration of the tricyclic intermediate (995) (60TL(25)44>. Vasicine has bronchodilatory activity of a low order. Two related unnamed alkaloids (997) and (998) were obtained in 1965 from members of the Araliaceae family, viz. Mackinlaya subulata and M. macrosciadia both had been synthesized earlier (66AJC151). [Pg.148]

The crude drug, Adhatoda vasica, is used in India as a remedy for asthma. According to Chopra, vasicine produces broncho-dilation and might be used clinically as an expectorant. A detailed pharmacological examination of peganine in comparison with harmine has been made by Tutaev and Makarova. ... [Pg.620]

It was recently observed that a iplant, Adhatoda vasica, long used in Indian herbal medicine (the source of many therapeutic leads) for the relief of cough and respiratory tract congestion, did appear to reduce the quantity and viscosity of sputum. The plant was studied and its active alkaloid named vasicine. The tricyclic quinazoline structure (XXVIII) was then reduced to fragments and a series of derivatives prepared [350]. From these bromhexine (XXIX, Na 274, Bisolvon)... [Pg.44]

Certain alkaloids such as vasicine obtained from plant Adhatoda vasica act as potent expectorant and mucolytic agent. Bromhexine, a derivative of vasicine depolymerises mucopolysaccharides directly and by liberating lysosomal enzymes. Another compound acetylcysteine opens disulfide bonds in mucoproteins present in sputum and decrease its viscosity. Carbocisteine acts in same manner. [Pg.230]

In 1888, Hooper first investigated the pharmacological action of an extract of Adhatoda vasica Nees containing compound 184. In 1925, Ghose and Sen isolated this component and named it vasicine. In 1934, Spath and Nikawitz isolated an alkaloid from Peganum harmala and named it pe-ganine, but soon afterward Sp th and Kuffner showed it to be identical with vasicine. This alkaloid (184) was found not only in Adhatoda... [Pg.317]

Arabic traditional plants from Egypt. Ali et al. [276] tested 20 different Arabic traditional plants from Egypt. Adhatoda vasica and Peganum harmala showed inhibitory effect on AChE. Ferula assa-foetida, Syzygium aromaticum, and Zingiber officinalis showed activity against COX-1 enzyme. Potent radical scavenging activity was demonstrated in Terminalia chebula, T. arjuna, and Emblica officinalis extracts. [Pg.414]

ADHATODA The leaves of Adhatoda vasica, Nees, family Acanthaceae, are used in India. The constituents include the alkaloid vasicine (peganine), which has a mucolytic effect, i.e. lowers the viscosity of the bronchial mucus by depolymerisation and makes it more liquid, so that it can be transported. The mucocilliary transport of mucous to the periphery depends on the mucous having certain rheological properties. The drug is used as mucolytic in cough mixtures in the form of a liquid extract. [Pg.126]
