Khan A, Ikram M, Rehman S, Khan R, Puduvalli VK, Jadoon A, Khan M, Alasmari F, AlAsmari AF. Triethylammonium salt of a synthesized dicoumarol: Structural insight and human anti-glioblastoma activities. Heliyon 2023; 9:e17601. [PMID: 37456028 PMCID: PMC10338367 DOI: 10.1016/j.heliyon.2023.e17601] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Revised: 06/18/2023] [Accepted: 06/22/2023] [Indexed: 07/18/2023] Open
Abstract
Glioblastoma multiforme (GBM) is the most common and primary brain tumor with poor prognosis. They are removed by following tedious and life threatening surgeries. GBM stem cells (GSCs) are the main source of tumor recurrence after surgery. Hence, drugs are designed to overcome the recurrent glioblastoma malignant cells. Currently used chemotherapies are not cost effective as well as bear resistance. New and effective chemotherapeutic compounds are developed to overcome the intrinsic and acquired resistance. Dicoumarol derivative 3,3'-[(4-methoxyphenyl)methanediyl]bis(4-hydroxy-2Hchromen-2-one) (HL) and its triethylammonium salt triethylammonium3-[(4-methoxyphenyl)(4-hydroxy-2-oxo-2H-chromen-3-yl)methyl]-2-oxo-2H-chromen-4-olate (L) were synthesized and characterized using spectral and analytical techniques. The deprotonated compound L was further studied structurally using single crystal analysis. Cytotoxic studies against human glioblastoma cells A172 and LN229 were investigated both dose and time dependently and compared with the cytotoxicity of normal human astrocytes (NHA). The IC50 value of HL against A172 was found to be lying within the range 2.68-0.95 μM whereas against LN229 the range was found to be 9.55-0.85 μM. Similarly, the compound L revealed range of 1.9-0.271 μM against A172 and 1.2-0.27 μM against LN229. Cell cycle arrest was observed in GBM cells treated with L compared to the control group, which suggested that L may trigger apoptosis in GBM cells according to cytotoxicity and flow cytometry results. The antioxidant activity of synthesized compounds was also investigated using DPPH free radicals.

Abstract
The reaction between 3,3'-[(3-meth-oxy-4-hy-droxy-phen-yl)methanedi-yl]bis-(4-hy-droxy-2H-chromen-2-one) and tri-ethyl-amine in methanol yielded the title compound tri-ethyl-ammonium 3-[(4-hy-droxy-3-meth-oxy-phen-yl)(4-hy-droxy-2-oxo-2H-chromen-3-yl)meth-yl]-2-oxo-2H-chromen-4-olate, C6H16N+·C26H17O8- or (NHEt3)+(C26H17O8)-, which crystallized directly from its methano-lic mother liquor. The non-deprotonated coumarol substituent shares its H atom with the deprotonated coumarolate substituent in a short negative charge-assisted hydrogen bond in which the freely refined H atom is moved from its parent O atom towards the acceptor O atom, elongating the covalent O-H bond to 1.18 (3) Å. The respective H atom can therefore be described as being shared by two alcohol O atoms, culminating in the formation of an eight-membered ring.

Abstract
The title compound, [Cs(CH3COO)(C28H16O8)(C2H5OH)]·C2H5OH, is the product of the complexation between one vasarene analogue [1], bis ninhydrin naphthalene-1,3-diol and CsF, where the F(-) ion has reacted with residual acetic acid (AcOH), to form a [1]·CsOAc complex. The inter-molecular inter-actions with the multiple oxygen-containing functional groups of the ligand, as well as O-H⋯O hydrogen bonds involving the ethanol solvent mol-ecules, stabilize the complex, forming a chain along [100]. Additional parallel-displaced π-π stacking, with an inter-planar distance of 3.669 (1) Å, connect several unit cells in a three-dimensional supra-molecular structure, though, the larger size of AcO(-) (1.60 Å) compared to F(-) (1.33 Å) prevents the tight packing that was once achieved with other vasarene complexes of CsF.
