In this work, we report our investigation on the alane-trihalide (Al[X.sub.3], X = F, Cl, and Br) donor-acceptor complexes [X.sub.3]Al-Y[C.sub.4][H.sub.4] (Y = O in furan, Y = NH in pyrrole, and Y = S in thiophen) compared to the alane [H.sub.3]Al-Y[C.sub.4][H.sub.4] ones.
Keeping in mind the bioactivity of Schiff bases, a novel Schiff base bearing furan and thiophen rings has been synthesized and evaluated for the in vitro antifungal activity against Fusarium oxysporum f.sp albedinis FAO fungal strains and the anticancer activity toward breast (MDA-MB231) and colorectal (LoVo) human cell lines cancers.
