In the 1920s, the Nobel Prize winner Otto Warburgobserved a marked increase in glycolysis and enhanced lactateproduction in tumor cells even when maintained in conditions ofhigh oxygen tension (termed Warburg effect), leading to widespreadconcerns about the metabolic changes in human types of cancer(). Either as a consequence or asa cause, alterations of cancer cell-intrinsic metabolism have beenconsidered as essential hallmarks of cancer. Among these metabolicchanges, fatty acid biosynthesis was found elevatedin the majority of human types of cancer, such as prostate(), colorectal (), ovarian (), bladder (), esophageal (), gastric (), lung (), endometrial (), breast () and soft tissue sarcomas (). Fatty acid synthase (FASN) isregarded as a key regulator of fatty acid synthesisand was widely found upregulated in a wide variety of humanmalignancies and their pre-neoplastic lesions. Recent studies alsoreveal that FASN is associated with the stage of cancer andindicate a poor prognosis ().Thus, FASN could be considered as a reliable predictor ofrecurrence and disease-free survival along with neo-plastic stage(). treatmentwith inhibitors of FASN has been proven to lead to markedlydecreased survival in human cancer xenografts () and silencing of the FASN gene bysiRNA also inhibits cancer cell growth and ultimately inducescancer cell apoptosis ().Therefore, agents that inhibit FASN and the fatty-acid synthesis pathways could be considered as novelantitumor strategies.
C9-Substituted phenanthrene-based tylophorine derivatives (PBTs) (13-36) were synthesized and evaluated as in vitro anticancer agents against the human A549 lung cancer cell line. Twelve active compounds were further examined against DU-145 (prostate), ZR-751 (breast), KB (nasopharyngeal), and KB-Vin (multidrug resistant KB subline) human cancer cell lines. They showed potent cytotoxic activity against both wild type and matched multidrug resistant KB cell lines, and displayed notable selectivity toward DU-145 (prostate) and ZR-751 (breast) cancer cell lines. The mode of action of this class may be distinctly different from that of other cancer chemotherapeutic compounds. Three PBT analogs were also evaluated in a murine model. Compound 24b showed modest in vivo antitumor activity against human A549 xenograft in nude mice as well as potent in vitro cytotoxic activity, and thus, is a promising anticancer lead compound.
