Abstract
Aims:
This work aims to widen the scope of methodologies to prepare functionalized
N-alkenylcarbazates.
Background:
Alkenylcarbazates are generally prepared via Aza-Baylis-Hillman reactions, nucleophilic
attack on ketones or a tandem carbometallation/amidation reaction of alkynes.
Objective:
The objective of this work is to develop a method to prepare functionalized Nalkenylcarbazates
that alleviates the problem encountered in the above methods (use of electron
deficient alkenes, use of stoiechiometric amounts of metal, access to symmetrical dicarbazates only).
Methods:
Use of copper-catalyzed cross-coupling between vinylic diiodide and carbazates to prepare
functionalized N-alkenylcarbazates.
Results:
Various β-iodovinylcarbazates were synthesized with up to good yields. The highest
yields were obtained using dicarbazates. Functionalization of β-iodovinylcarbazate demonstrated
that the vinyl iodide moiety of these molecules can be substituted by a variety of functional
groups via transition metal-catalyzed coupling reactions.
Conclusion:
Copper-catalyzed cross-coupling reaction is efficient to prepare functionalized
N-alkenylcarbazates.

Distinct Mechanisms of Cytotoxicity in Novel Nitrogenous Heterocycles: Future Directions for a New Anti-Cancer Agent. Molecules 2022; 27:molecules27082409. [PMID: 35458609 PMCID: PMC9029529 DOI: 10.3390/molecules27082409] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2022] [Revised: 03/30/2022] [Accepted: 04/05/2022] [Indexed: 02/04/2023] Open
Abstract
Electron-rich, nitrogenous heteroaromatic compounds interact more with biological/cellular components than their non-nitrogenous counterparts. The strong intermolecular interactions with proteins, enzymes, and receptors confer significant biological and therapeutic properties to the imidazole derivatives, giving rise to a well-known and extensively used range of therapeutic drugs used for infections, inflammation, and cancer, to name a few. The current study investigates the anti-cancer properties of fourteen previously synthesized nitrogenous heterocycles, derivatives of imidazole and oxazolone, on a panel of cancer cell lines and, in addition, predicts the molecular interactions, pharmacokinetic and safety profiles of these compounds. Method: The MTT and CellTiter-Glo® assays were used to screen the imidazole and oxazolone derivatives on six cancer cell lines: HL60, MDA-MB-321, KAIMRC1, KMIRC2, MCF-10A, and HCT8. Subsequently, in vitro tubulin staining and imaging were performed, and the level of apoptosis was measured using the Promega ApoTox-Glo® triplex assay. Furthermore, several computational tools were utilized to investigate the pharmacokinetics and safety profile, including PASS Online, SEA Search, the QikProp tool, SwissADME, ProTox-II, and an in silico molecular docking study on tubulin to identify the critical molecular interactions. Results: In vitro analysis identified compounds 8 and 9 to possess the most significant potent cytotoxic activity on the HL60 and MDA-MB-231 cell lines, supported by PASS Online anti-cancer predictions with pa scores of 0.413 and 0.434, respectively. In addition, compound 9 induced caspase 3/7 dependent-apoptosis and interfered with tubulin polymerization in the MDA-MB-231 cell line, consistent with in silico docking results, identifying binding similarity to the native ligand colchicine. All the derivatives, including compounds 8 and 9, had acceptable pharmacokinetics; however, the safety profile was suboptimal for all the tested derivates except compound 4. Conclusion: The imidazole derivative compound 9 is a promising anti-cancer agent that switches on caspase-dependent apoptotic cell death and modulates microtubule function. Therefore, it could be a lead compound for further drug optimization and development.
