Chemical Reviews, Journal Year: 2022, Volume and Issue: 122(16), P. 13235 - 13400

Published: Aug. 2, 2022

It is not a coincidence that both chirality and noncovalent interactions are ubiquitous in nature synthetic molecular systems. Noncovalent interactivity between chiral molecules underlies enantioselective recognition as fundamental phenomenon regulating life human activities. Thus, represent the narrative thread of fascinating story which goes across several disciplines medical, chemical, physical, biological, other natural sciences. This review has been conceived with awareness modern attitude toward its consequences needs to be founded on multidisciplinary approaches disclose basis essential phenomena domain With primary aim discussing this topic an integrated way, comprehensive pool rational systematic information provided, concerns fundamentals chirality, description interactions, their implications processes occurring different contexts. A specific focus devoted enantioselection chromatography electromigration techniques because unique feature "multistep" processes. second motivation for writing make clear statement about state art, tools we have at our disposal, what still missing fully understand mechanisms underlying recognition.

Recent advances in targeting the “undruggable” proteins: from drug discovery to clinical trials

Signal Transduction and Targeted Therapy, Journal Year: 2023, Volume and Issue: 8(1)

Published: Sept. 6, 2023

Abstract Undruggable proteins are a class of that often characterized by large, complex structures or functions difficult to interfere with using conventional drug design strategies. Targeting such undruggable targets has been considered also great opportunity for treatment human diseases and attracted substantial efforts in the field medicine. Therefore, this review, we focus on recent development discovery targeting “undruggable” their application clinic. To make review well organized, discuss strategies proteins, including covalent regulation, allosteric inhibition, protein–protein/DNA interaction targeted nucleic acid-based approach, immunotherapy others.

Naturally derived indole alkaloids targeting regulated cell death (RCD) for cancer therapy: from molecular mechanisms to potential therapeutic targets

Journal of Hematology & Oncology, Journal Year: 2022, Volume and Issue: 15(1)

Published: Sept. 14, 2022

Abstract Regulated cell death (RCD) is a critical and active process that controlled by specific signal transduction pathways can be regulated genetic signals or drug interventions. Meanwhile, RCD closely related to the occurrence therapy of multiple human cancers. Generally, subroutines are key tumorigenesis, which contributed our better understanding cancer pathogenesis therapeutics. Indole alkaloids derived from natural sources well defined for their outstanding biological pharmacological properties, like vincristine, vinblastine, staurosporine, indirubin, 3,3′-diindolylmethane, currently used in clinic under clinical assessment. Moreover, such compounds play significant role discovering novel anticancer agents. Thus, here we systemically summarized recent advances indole as agents targeting different subroutines, including classical apoptosis autophagic signaling crucial other ferroptosis, mitotic catastrophe, necroptosis, anoikis, cancer. further discussed cross talk between mediated combined strategies (e.g., 3,10-dibromofascaplysin with olaparib) exhibit therapeutic potential against various cancers regulating subroutines. In short, information provided this review on regulation targets expected beneficial design molecules greater thereby facilitating development new therapy. Graphic abstract
