Special Issue Information

Dear Colleagues,

Cancer is a major health issue worldwide, with an increasing global burden in the coming years. Some malignancies, such as colorectal, breast, prostate, and pancreatic cancers, are still incurable in advanced stages. Thus, more effective anticancer drugs are always urgently needed. The process of drug discovery is still risky, lengthy, and costly, and only a few new anticancer drugs have received approval in recent years. Drug repurposing is an unconventional drug discovery approach to explore new disease indications from existing clinical drugs. Even shelved drugs that never enter or fail during clinical trials might be rescued if novel mechanisms of action (MOAs) or targets are identified. Polypharmacology describes the ability of a drug to affect more than one molecular target, which is now commonly accepted as a basic property of small molecules and serves as a foundational principle for drug repurposing. Exploring polypharmacology is highly useful for discovering drugs’ novel MOAs to improve their therapeutic efficacies and treat different diseases. The advantages of drug repurposing include a reduction in cost and the bypass of safety concerns because extensive drug data are often available.

This Special Issue will focus on the development of novel cancer therapy based on polypharmacology and drug repurposing strategies. We welcome original research articles and review articles in this field.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. BioChem is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Colorectal cancer (CRC) is a prevalent and deadly tumor worldwide. Understanding the molecular mechanisms underlying CRC development will improve treatment outcomes and patient survival. Natural molecules and metabolites from plants, such as Tillandsia usneoides, reduce tumor growth by modulating glucose metabolism and increasing reactive oxygen species (ROS). To shed light on the mechanism involved in the anti-tumor effects of T. usneoides, we evaluated the cytotoxic effect of the ethanolic extract of this plant on the colon cancer cell line SW480 through the activation of the peroxisome proliferator-activated receptor gamma (PPARγ), a nuclear receptor that plays a role on lipid metabolism and inflammation in cancer cells. To this end, we assessed the activation of PPARγ by T. usneoides extract in transactivation luciferase assays, as well as the cytotoxic effect of this extract on the SW480 cell line after knocking down PPARγ using shRNA. Our findings indicate that the T. usneoides extract exhibits cytotoxic effects on the SW480 cell line, potentially in the same way as PPARγ activator, pioglitazone, i.e., by increasing reactive oxygen species (ROS). In addition, both T. usneoides extract and pioglitazone exert lipogenic properties in the SW480 cells. Taken together, these results demonstrate that the T. usneoides extract decreases the viability of the colon cancer cell line SW480, at least in part, through the activation of PPARγ. This suggests the potential for further use of this plant in the treatment of other chronic diseases. Full article

Flavan-3-ol derivatives are polyphenolic compounds with multifunctional properties. One of the flavan-3-ol derivatives, green tea catechin epigallocatechin gallate, is known to have anticancer activity as one of its multifunctional properties. We have studied the synthesis of flavan-3-ol derivatives and conducted structure-activity relationship studies; we found that the fluorinated derivatives exhibited high toxicity against HeLa and A549 cells. It was confirmed that the cytotoxicity was affected by the conformation of the flavan-3-ol skeleton and that the 2,3-cis form was dominant. The addition of fluorinated compounds increased the amount of intracellular mitochondrial superoxide, abolished the membrane potential of mitochondria, and, interestingly, formed granular aggregates containing mitochondria. When the level of LC3-II, a marker of autophagy induction, was confirmed, it suggested that the addition of the fluorinated compounds promoted autophagy. These results suggest that the novel highly cytotoxic fluorinated flavan-3-ol compound synthesized in this study promotes autophagy and induces cell death by triggering mitochondrial dysfunction. We believe that these results suggest the possibility of conferring more functionality through structural transformations of flavan-3-ol derivatives. Full article
