Complete assignments of the 1H and 13C NMR spectra of 15 limonoids
Rodriguez, Benjamin
, p. 206 - 212 (2003)
Unambiguous and complete assignments of 1H and 13C NMR chemical shifts for 15 limonoids, eight of them found in natural sources and seven other synthetic derivatives, are presented. The assignments are based on 2D shift-correlated [

Azadirone 1, a limonoidal constituent of Azadirachta indica is found to possess potent cytotoxic activity against a panel of human cancer cell lines in our in vitro studies. In vitro screening of a number of semi-synthetic analogues of 1 revealed that the α,β-unsaturated enone moiety or its equivalent conjugated system in A-ring, C-7 acetyloxy/chloroacetyloxy or keto group in B-ring and the furan moiety are responsible for the activity of 1 and its analogues. Compound 1 and two of the semi-synthetic analogues 10 and 13 were found to possess good in vivo antitumor activity in modified hollow fiber animal models.

Azadirone (I) has been hydrolysed and the resulting alcohol (VIII) oxidised to a 7-keto compound (IX) which on Barton oxidation yields 1,2-epoxycedrelone (XIII), cedrelone (VII) and two carboxylic acids (XIV) and (XV) derived by a benzilic acid rearrangement.Thus the neem limonoids have been correlated with cedrelone.
