A new series of benzimidazole/benzoxazole linked beta-carbolines (9a-j) were rationally designed and synthesized by combining two different anti-cancer fragments. The new hybrid beta-carbolines are subjected to anti-cancer screening against four different human cancer cell lines such as MCF-7 (breast), A549 (lung), Colo-205 (colon) and A2780 (ovarian) by using standard MIT assay. These hybrid beta-carbolines exhibited significant and high fold anti-cancer activity against MCF-7 cell lines than reference standard. They are also proved to be effective against A549 and Colo-205 cell lines. Further, compound 9b, 9c from benzimidazole and 9i from benzoxazole series have exhibited maximum anti-cancer activity among these hybrid beta-carbolines. Later, all of the hybrid beta-carbolines were subjected to molecular interaction analysis against a few selected kinase targets such as cdc-like kinase (CLK-1 to CLK-4), epidermal growth factor reductase (EGFR) kinase, protein (ATR) kinase along with APC-Asef interface. The violin plot of binding energies of 9a-9j have suggested them as good kinase binders. Result interpretation suggested hybrid beta-carbolines as promising CLK binders. The anti-cancer data of new hybrid beta-carbolines against MCF-7 cell lines are in agreement with parent beta-carboline skeleton. (C) 2020 Elsevier B.V. All rights reserved.

Despite an increasing number of studies that have investigated mechanochemical effects in polymers, the number of polymers whose fluorescence characteristics change upon exposure to mechanical stress is still limited. We here report the investigation of a mechanofluorophore based on an aliphatic ester of 2-(2′-hydroxyphenyl)benzoxazole. The free benzoxazole displays green photoluminescence, which is associated with an excited state intramolecular proton transfer (ESIPT) process, whereas aliphatic esters of this compound emit blue light. When poly(methyl acrylate) containing an esterified benzoxazole mechanophore at the center of each chain molecule was exposed to ultrasound, a significant reduction of the molecular weight and pronounced changes of the photoluminescence emission and UV-vis absorption spectra were observed. The optical changes and the fact that the time-traces for molecular weight decrease and formation of the ESIPT capable species mirror each other indicate that the mechanophore is preferentially cleaved upon sonication and that such cleavage restores the 2-(2′-hydroxyphenyl)benzoxazole motif. The concept of mechanical activation of ester-protected ESIPT dyes, and more broadly of other hydroxyl group carrying fluorophores that change their emission properties upon ester formation and cleavage, should be general and allow access to a range of other mechanofluorophores.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 540-37-4, in my other articles.

New discoveries in chemical research and development in 2021. The transformation of simple hydrocarbons into more complex and valuable products has revolutionised modern synthetic chemistry. In an article, author is Li, Changming, once mentioned the application of 540-37-4, Recommanded Product: 4-Iodoaniline, Name is 4-Iodoaniline, molecular formula is C6H6IN, molecular weight is 219.023, category is benzoxazole. Now introduce a scientific discovery about this category.

The effects of the heteroatom and position on excited-state intramolecular proton transfer (ESIPT) of 2-[4 ‘-(N-4,6-dichloro-1,3,5-triazi-n-2-yl)2 ‘ hydroxyphenyl]benzoxazole (4THBO) have been investigated via time-dependent density functional theory studies. The heteroatoms refer to O and S atoms, and the position effect refers to the N-4,6-trichloro-1,3,5-triazin-2-yl (TCT) substituents in the para and meta positions. The configuration of the four compounds (4THBO, 4THBT, 5THBO and 5THBT) was optimized and the bond lengths, bond angles and infrared spectra of the atoms participating in the proton transfer in the S0 and S1 states were studied. The occurrence of ultrafast ESIPT in the four compounds was demonstrated. Moreover, the potential energy curves of the S0 and S1 states were constructed, and the effects of the heteroatom substitution and substituent position changes on the ESIPT mechanism of the four 4THBO derivatives were analyzed. The results show that the ESIPT barrier of the S atom substitution in the excited state is lower than that of the O atom-substituted molecule, and the energy barrier of the substituent (TCT) in the meta-position is significantly smaller than that in the para-position. These results indicate that the substitution of the S heteroatom promotes the ESIPT of the 4THBO compound and that the substituent (TCT) in the para position is more prone to proton transfer than that in the meta position. Our work could provide a theoretical basis for further experiments.

Phortress is an anticancer prodrug, which has active metabolite (5F-203) being potent agonist of the aryl hydrocarbon receptor (AhR). The 5F-203 switches on cytochrome P450 CYP1A1 gene expression and thus exhibits anticancer activity. In this study, it is aimed to obtain new phortress analogues by bioisosteric replacement of benzothiazole core in the structure to benzoxazole ring system. Synthesis of compounds (3a-3p) were performed according to literature methods. Their structures were elucidated by IR, H-1 NMR, C-13 NMR, 2D-NMR and HRMS spectroscopic methods. Cytotoxicity (MTT), inhibition of DNA synthesis and flow cytometric analysis assays were applied to determine anticancer activity of the compounds on colon (HT-29), breast (MCF7), lung (A549), liver (HepG2) and brain (C6) carcinoma cell types. When compared reference agent doxorubicin, compounds 3m and 3n displayed very attractive anticancer effect against carcinogenic cell lines. Due to structural similarity to phortress, biotransformation studies for 3m and 3n were examined by LCMS-IT-TOF system and probable metabolites of these compounds were determined. Induction potential of these compounds on CYP1A1/2 enzymes was also investigated to clarify possible mechanism of action. Interaction modes between CYP1A1 enzyme and compound 3n or its some metabolites were investigated by docking studies. In conclusion, findings of these study indicate that compounds 3m and 3n possess significant anticancer activity, probably with the same mechanism of action to Phortress.

Water-Soluble Benzazole Dyes Fluorescent by ESIPT: Structural Characterization, Photophysical Properties and Its Application as a Probe for Direct Staining of Helminths

A series of four water-soluble benzazole dyes that emit fluorescence by the excited state intramolecular proton transfer (ESIPT) mechanism were structurally characterized by Fourier transform infrared spectroscopy (FTIR), H-1 and C-13 nuclear magnetic resonance (NMR) attached proton test (APT) and mass spectrometry. Their photophysical properties were systematically studied by UV-absorption and fluorescence emission. Some photophysical parameters were obtained by semi-empirical PM3 and ZINDO methods, and related to experimental photophysical data. Changes in the absorption and fluorescence emission spectra as well as conformational equilibrium between different species were investigated in solvents of different polarities and under different pH conditions. These benzazole dyes emit dual fluorescence emission in the blue-orange region with a Stokes shift between 2617-12337 cm(-1). In general, these dyes are potentially interesting for studies of biological systems in an aqueous environment due to the presence of groups that increase aqueous solubility and reactivity with biomolecules. The present dyes were successfully used as new probes by means of direct staining of larvae. The obtained results indicate that these fluorescent dyes permit a quick, easy and selective visualization of larvae.
