    Description

    DETAILED DESCRIPTION OF THE INVENTION

    [0396] The precursors (Z)-3-(3,4,5-trimethoxystyryl)aniline of formula 7(a-o) have been prepared using literature method (Keith A. Monk, a Rogelio Siles, a Mallinath B. Hadimani, a Benon E. ugabe, a J. Freeland Ackley, a Scott W. Studerus, a Klaus Edvardsen, b Mary Lynn Trawick, a Charles M. Garner, a Monte R. Rhodes, c George R. Pettit c and Kevin G. Pinney a,*, Bioorganic & Medicinal Chemistry 14 (2006) 3231-3244). The crucial intermediates for the preparation of precursors (Z)-3-(3,4,5-trimethoxystyryl)aniline formula 7(a-o) are (Z)-1,2,3-trimethoxy-5-(3-nitrostyryl)benzene 6(a-o) have been prepared using literature methods (Kevin G. Pinney, a,* Maria P. Mejia, a Victor M. Villalobos, a Brent E. Rosenquist, a George R. Pettit, b Pascal Verdier-Pinard c and Ernest Hamel c, Bioorganic & Medicinal Chemistry 8 (2000) 2417±2425).

    [0397] These new 3,4,5-trimethoxystyrylaryl sulfonamide derivatives have shown promising anticancer activity in various cancer cell lines. The molecules synthesized are of immense biological significance. This resulted in design and synthesis of new congeners as illustrated in scheme 1 which comprise: The reaction between (Z)-3-(3,4,5-trimethoxystyryl)aniline of formula 7(a-o) and the benzene sulfonyl chlorides compounds of formulae a to y for the compounds (9a-9y to 23a-23y). [0398] 1. Stirring the amines at 0° C. and add benzenesulfonylchlorides slowly to the reaction mixture, maintain for 2-3 h at room temperature to obtain the compounds (9a-y to 23a-23y) respectively. [0399] 2. Synthesis of (Z)-3,4,5-trimethoxystyryl benzenesulfonamides. [0400] 3. Purified by the column chromatography using different solvents like ethyl acetate and hexane [0401] 4. The final step has been carried out by the (Z)-3-(3,4,5-trimethoxystyryl)aniline of formula 7(a-o) and substituted benzene sulfonyl chlorides in pyridine at 0° C. The compounds of formulae a to y for the compounds (9a-9y to 23a-23y)

    [0402] The key intermediates 3-substituted (Z)-3-(3,4,5-trimethoxystyryl)aniline 7(a-o) are prepared in five sequential steps. 3,4,5-Trimethoxybenzaldehyde (1) reduces with sodium borohydride in methanol gives (3,4,5-trimethoxyphenyl)methanol (2). This was further reacted with PBr.sub.3 in CH.sub.2Cl.sub.2 to produce 5-(bromomethyl)-1,2,3-trimethoxybenzene (3), then this was further reacted with triphenylphosphine in toluene to give 3,4,5-trimethoxybenzyltriphenylphosphonium bromide (4) in good yields. The obtained witting salt was reacted with substituted benzaldehydes (5a-5o) in presence of NaH in CH.sub.2C1.sub.2 to produce (Z)-1,2,3-trimethoxy-5-(substituted-nitrostyryl)benzene 6(a-o) and (E)-1,2,3-trimethoxy-5-(substituted-nitrostyryl)benzene in (1:1)% of yield. Z)-1,2,3-trimethoxy-5-(substituted nitrostyryl)benzene reduced with Zn ammoniumformate in methanol produced (Z)-3-(3,4,5-trimethoxystyryl)aniline.
