The native chemical ligation reaction (NCL) involves reacting a C-terminal peptide thioester with an N-terminal cysteinyl peptide to produce a native peptide bond between the two fragments. This reaction has considerably extended the size of polypeptides and proteins that can be produced by total synthesis and has also numerous applications in bioconjugation, polymer synthesis, material science, and micro- and nanotechnology research. The aim of the present review is to provide a thorough mechanistic overview of NCL and extended methods. The most relevant properties of peptide thioesters, Cys peptides, and common solvents, reagents, additives, and catalysts used for these ligations are presented. Mechanisms, selectivity and reactivity are, whenever possible, discussed through the insights of computational and physical chemistry studies. The inherent limitations of NCL are discussed with insights from the mechanistic standpoint. This review also presents a palette of O,S-, N,S-, or N,Se-acyl shift systems as thioester or selenoester surrogates and discusses the special molecular features that govern reactivity in each case. Finally, the various thiol-based auxiliaries and thiol or selenol amino acid surrogates that have been developed so far are discussed with a special focus on the mechanism of long-range N,S-acyl migrations and selective dechalcogenation reactions.

Olaparib is a PARP inhibitor (PARPi). For patients bearing BRCA1 or BRCA2 mutations, olaparib is approved to treat ovarian cancer and in clinical trials to treat breast and pancreatic cancers. In BRCA2-defective patients, PARPi inhibits DNA single-strand break repair, while BRCA2 mutations hamper double-strand break repair. Recently, we identified a series of triazole derivatives that mimic BRCA2 mutations by disrupting the Rad51-BRCA2 interaction and thus double-strand break repair. Here, we have computationally designed, synthesized, and tested over 40 novel derivatives. Additionally, we designed and conducted novel biological assays to characterize how they disrupt the Rad51-BRCA2 interaction and inhibit double-strand break repair. These compounds synergized with olaparib to target pancreatic cancer cells with functional BRCA2. This supports the idea that small organic molecules can mimic genetic mutations to improve the profile of anticancer drugs for precision medicine. Moreover, this paradigm could be exploited in other genetic pathways to discover innovative anticancer targets and drug candidates.

Background: A series of 2-(1H-benzo[d]imidazol-2-ylthio)-N-(substituted 4-oxothiazolidin-3-yl) acetamides was synthesized and characterized by physicochemical and spectral means. The synthesized compounds were evaluated for their in vitro antimicrobial activity against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Candida albicans and Aspergillus niger by tube dilution method. The in vitro cytotoxicity study of the compounds was carried out against human colorectal (HCT116) cell line. The most promising anticancer derivatives (5l, 5k, 5i and 5p) were further docked to study their binding efficacy to the active site of the cyclin-dependent kinase-8. Results: All the compounds possessed significant antimicrobial activity with MIC in the range of 0.007 and 0.061 muM/ml. The cytotoxicity study revealed that almost all the derivatives were potent in inhibiting the growth of HCT116 cell line in comparison to the standard drug 5-fluorouracil. Compounds 5l and 5k (IC50 = 0.00005 and 0.00012 muM/ml, respectively) were highly cytotoxic towards HCT116 cell line in comparison to 5-fluorouracil (IC50 = 0.00615 muM/ml) taken as standard drug. Conclusion: The molecular docking studies of potent anticancer compounds 5l, 5k, 5i and 5p showed their putative binding mode and significant interactions with cyclin-dependent kinase-8 as prospective agents for treating colon cancer.

Isatin and azole moieties, which have the ability to form various noncovalent interactions with different therapeutic targets, are common pharmacophores in drug development. Isatin and azole derivatives possess promising in vitro and in vivo anticancer activity, and many of them, such as semaxanib, sunitinib, and carboxyamidotriazole, could be used to treat various cancers. Thus, it is conceivable that hybridization of the isatin moiety with azole may provide a valuable therapeutic intervention for the treatment of cancer. Substantial efforts have been made to develop isatin?azole hybrids as novel anticancer agents, and some of the isatin?azole hybrids exhibited considerable activity. This review emphasizes isatin?azole hybrids with potential anticancer activity, covering articles published between 2010 and 2019. The structure?activity relationships as well as the mechanisms of action are also discussed to provide insights for the rational design of more effective candidates.

Background: Schistosomiasis is a neglected disease, which affects millions of people in developing countries. Its treatment relies on a single therapeutic alternative, the praziquantel. This situation may lead to drug resistance which, in turn, made urgent the need for new antischistosomal agents. N-acylhydrazones are usually explored as good antimicrobial agents, but the vanillin-related N-acylhydrazones have never been tested by their antiparasitic potential. Objective: Herein, we report the synthesis of seven analogues, three of them unpublished, their biological investigation against Schistosoma mansoni and Target Fishing studies. Methods: The compounds were synthesized following classical synthetical approaches. The anthelmintic potential was assessed as well as their cytotoxicity profile. Confocal laser scanning microscopy and target fishing study were performed to better understand the observed antischistosomal activity. Results: Compound GPQF-407 exhibited good antischistosomal activity (47.91 muM) with suitable selectivity index (4.14). Confocal laser scanning microscopy revealed that it triggered severe tegumental destruction and tubercle disintegration. Target fishing studies pointed out some probable targets, such as the serine-threonine kinases, dihydroorotate dehydrogenases and carbonic anhydrase II. Conclusion: The GPQF-407 was revealed to be a promising antischistosomal agent which, besides presenting the N-acylhydrazone privileged scaffold, also could be easily synthesized on large scales from commercially available materials.

Olefin aminations are important synthetic technologies for the construction of aliphatic C-N bonds. Here we report a catalytic protocol for olefin hydroamidation that proceeds through transient amidyl radical intermediates that are formed via proton-coupled electron transfer (PCET) activation of the strong N-H bonds in N-alkyl amides by an excited-state iridium photocatalyst and a dialkyl phosphate base. This method exhibits a broad substrate scope, high functional group tolerance, and amenability to use in cascade polycyclization reactions. The feasibility of this PCET protocol in enabling the intermolecular anti-Markovnikov hydroamidation reactions of unactivated olefins is also demonstrated.
