Abstract

The Special Issue “Molecules from Side Reactions” is a collection of papers reporting on the synthesis and characterization of the molecules that come from unexpected synthetic routes. This is the first example of a Special Issue based on such a topic, notwithstanding that all synthetic chemists have isolated a side product during a chemical reaction. Instead of continuing to store the side products in the freezer, I have thought to give them the dignity of publication, making them available to the scientific community. The short manuscripts collected here respect the principle of “one compound per paper” and have the purpose of preserving the molecular diversity deriving from a chemical reaction. The molecular scaffolds are unexpected and intriguing, and could be useful starting points or intermediates for exploring novel reactions.

Abstract

The Special Issue "Anticancer Drugs 2021" of Pharmaceuticals is focused on recent significant advances in the design, synthesis, molecular mechanism of action and therapeutic applications of anticancer drugs. This collection of preclinical research papers and reviews includes designed chemotherapeutic agents, targeted therapies and biological agents. The rationalization for the biological activity of these drugs is presented, which helps to guide the design of more effective agents. Structure–activity relationships, together with the biological context in which targets are selected for oncology drug development, are also considered.

Abstract

The health benefits of food, plants, fruits, and seaweeds stem from the biological activities of their constituents—namely, secondary metabolites. The study of secondary metabolites and their potential to treat and/or prevent a number of diseases has become a research topic of growing interest for biologists, pharmacists, and chemists. Notably, in order to propose a compound as a potential new drug with pharmacological effects, the chemical structure of this compound and its biological activity against a given target must be well established. The Special Issue, “Isolation and Identification of Bioactive Secondary Metabolites”, considers species beyond their nutritional value and identifies instances of wider and more efficient use, thereby contributing to a more sustainable management of natural resources. The fifteen articles published in this Special Issue reflect the latest research trends, and consider the isolation, identification, and assessment of the beneficial effects of secondary metabolites from both edible and inedible species. Thus, these contributions collectively demonstrate that these compounds, and their plants of origin, should be valued beyond their nutritional benefits.

Abstract

Heterocycles feature widely in natural products, agrochemicals, pharmaceuticals and dyes, and their synthesis is of great interest to synthetic chemists in both academia and industry. The contributions of recent applications of new methodologies in C–H activation, photoredox chemistry, cross-coupling strategies, borrowing hydrogen catalysis, multicomponent and solvent-free reactions, regio- and stereoselective syntheses, as well as other new, attractive approaches for the construction of heterocyclic scaffolds are of great interest. This Special Issue is dedicated to featuring the latest research that is ongoing in the field of heterocyclic synthesis. It is expected that most submissions will focus on five- and six-membered oxygen and nitrogen-containing heterocycles, but structures incorporating other rings/heteroatoms will also be considered. Original research (communications, full papers and reviews) that discusses innovative methodologies for assembling heterocycles with potential application in materials, catalysis and medicine are therefore welcome.

Abstract

This book is a printed edition of the Special Issue entitled “Anticancer Agents: Design, Synthesis and Evaluation” that was published in Molecules. Two review articles and thirty research papers are included in the Special Issue. Three second-generation androgen receptor antagonists that have been approved by the U.S. FDA for the treatment of prostate cancer have been reviewed. Identification of mimics of protein partners as protein-protein interaction inhibitors via virtual screening has been summarized and discussed. Anticancer agents targeting various protein targets, including IGF-1R, Src, protein kinase, aromatase, HDAC, PARP, Toll-Like receptor, c-Met, PI3Kdelta, topoisomerase II, p53, and indoleamine 2,3-dioxygenase, have been explored. The analogs of three well-known tubulin-interacting natural products, paclitaxel, zampanolide, and colchicine, have been designed, synthesized, and evaluated. Several anticancer agents representing diverse chemical scaffolds were assessed in different kinds of cancer cell models. The capability of some anticancer agents to overcome the resistance to currently available drugs was also studied. In addition to looking into the in vitro ability of the anticancer agents to inhibit cancer cell proliferation, apoptosis, and cell cycle, in vivo antitumor efficacy in animal models and DFT were also investigated in some papers.
