The withanolides are steroidal lactones built on an ergostane skeleton of 28 carbons functionalized at carbons 1, 22 and 26, commonly known as the withanolide skeleton. The first withanolide to be isolated and characterized was withaferin A, Fig. (1), isolated in 1965 almost simultaneously by Lavie from Withania somnifera and by Kupchan from... [Pg.1019]

Withanolide-containing plants are widely used for hair care. Datura metel, or Datura, is a widely recommended remedy for the treatment of dandruff. Withania somnifera, also known as ashwagandha or Indian ginseng, is the most widely used withanolide-containing plant in the Ayurvedic medicinal system for... [Pg.3476]

Kuroyanagi and his coworkers evaluated a series of sixteen withanolides, isolated from Withania somnifera, for their cell differentiation inducing ability and found that withaferin A (2), withanolide D (24), dihydrowithanolide D (59), and 27-hydroxywithanolide D (60) were potent cell differentiation inducers against the Ml cells [83]. It was further concluded that all these withanolides have a similar 4)S-hydroxy-5) -6)S-epoxy-2-ene-l-one moiety in ring A, apparently responsible for their cell differentiation inducing activity. [Pg.3481]

However, withaferin-A, which was the first active principle isolated from Withania somnifera and also constituted the first member of a new class of phytosteroids (the withanolides), produced immunosuppression. Thus, it inhibited adjuvant arthritis in rats, graft vs host reaction in chicken, xenograft vs host reaction in mice, and depleted murine splenic cells in vitro [38-41]. This effect has been attributed to the glucocorticoid-like structure of withaferin-A [39]. Withania somnifera also reduces acute phase reactants [8] as well as a2-macroglobulin during inflammation. [Pg.306]

Co-occurrence of lactol-type withasteroids and steroidal alkaloids/glycoalkaloids has been demonstrated in two Solamm spp. S. ciliatum, S. sisymbrifolium). However, there is no report on co-occurrence of these alkaloids and withanolides. In a few taxa even withanolides co-occur surprisingly with different types of tropane alkaloids, i.e., hyoscyamine-type tropanes fowDatura spp., Hyoscyamus niger) or non-hyoscyamine-type tropanes and related alkaloids Nicandra physalodes, Physalis alkekengi, P. peruviana, Withania somnifera) for details see Tables 3.1 and 3.8. [Pg.480]

Use of Withania somnifera as a valuable and very popular drug in Ayurvedic medicine (Ray and Gupta 1994) and Physalis alkekengi in Chinese medicine are two outstanding examples for an extensive significance of withanolide-containing... [Pg.480]

Five withanolides isolated from Withania somnifera [mdAjuga bracteosa Benth. (Lamiaceae)] were shown to be novel natural cholinesterase (AChE) inhibitors with spasmolytic and calcium antagonistic properties. Thus, they represent leads or even possible drug candidates for treatment of Alzheimer s disease or related dementia (Choudhary et al. 2004, 2005). Three withanolides were found to be linear mixed-type inhibitors of AChE, the remaining two were non-competitive inhibitors, whereas all... [Pg.482]

Chemical studies on the leaf constituents of Acnistus arborescens [200], Withania somnifera [201-204], W. coagulens [205], and Jaborosa integrifoUa [206-208] have resulted in the discoveiy of the withanolides and jaboro-solides. One member of this group of steroidal lactones, withaferin A (L), has been found to be active against the experimental neoplasms W 256 and S 180. However, the therapeutic index of this compound is too small to warrant further pharmacological study [209]. [Pg.30]
