Background Candida susceptibility commonly occurs in breast cancer patients. Of which, Candida albicans is considered as a common pathogen causing candidiasis. Martinella iquitosensis (Bignoniaceae) is one of the species belonged to Martinella, distributed widely in Amazon basin. Its root extract yielded two complex substituted tetrahydroquinolines, Martinelline and Martinellic acid which were the first natural non-peptide bradykinin receptor antagonists identified. Findings In this study, a novel martinelline type analogue, named 2,3,3a,4,5,9b-hexahydro-8-phenoxy-4-(pyridin-2-yl)furo[3,2-c]quinoline, was synthesized and its preliminary anticancer activity and antifungal potential were investigated. This compound showed potential anticancer activity against MDAMB-231 breast cancer cells. Meanwhile it could enhance the fungistatic activity of miconazole against Candida albicans. Conclusions These findings provide an implication for the continue investigation and development of martinelline type analogues as therapeutic agents in the future.
