New steroidal oxazolines, benzoxazoles and benzimidazoles related to abiraterone and galeterone

Seven new oxazoline, benzoxazole and benzimidazole derivatives were synthesized from 3 beta-acetoxyandrosta-5,16-dien-17-carboxylic, 3 beta-acetoxyandrost-5-en-17 beta-carboxylic and 3 beta-acetoxypregn-5-en-21-oic acids. Docking to active site of human 17 alpha-hydroxylase/17,20-lyase revealed that all oxazolines, as well as benzoxazoles and benzimidazoles comprising Delta(16) could form stable complexes with enzyme, in which steroid moiety is positioned similarly to that of abiraterone and galeterone, and nitrogen atom coordinates heme iron, while 16,17-saturated benzoxazoles and benzimidazoles could only bind in a position where heterocycle is located nearly parallel to heme plane. Modeling of the interaction of new benzoxazole and benzimidazole derivatives with androgen receptor revealed the destabilization of helix 12, constituting activation function 2 (AF2) site, by mentioned compounds, similar to one induced by known antagonist galeterone. The synthesized compounds inhibited growth of prostate carcinoma LNCaP and PC-3 cells at 96 h incubation; the potency of 2′-(3-hydroxyandrosta-5,16-dien-17-yl)-4′,5′-dihydro-1′,3′-oxazole and 2′-(3 beta-hydroxyandrosta-5,16-dien-17-yl)-benzimidazole was superior and could inspire further investigations of these compounds as potential anti-cancer agents.

2,1,3-Benzothiadiazole dyes conjugated with benzothiazole and benzoxazole: Synthesis, solvatochromism and solid-state properties

Benzothiadiazole (BTD) dyes are an important class of N,S-containing heterocycles that have remarkable optical properties. In this work, two new 2,1,3-benzothiadiazole dyes conjugated with benzothiazole and benzoxazole moieties were synthesized and the optical properties in solutions and in the solid state were investigated. The BTD dyes were synthesized in a single step from cydization of ortho-diamino benzothiazole and ortho-diamino benzoxazole dyes. The photophysical behavior of BTD precursor’s benzoxazole and benzothiazole dyes were also investigated. The dyes present absorption in the UVB (280-315 nm) and UVA (315-400 nm) wavelength and fluorescence in the blue-green visible region. The solvatochromic properties of the dyes were investigated indifferent solvents taking into account the solvent orientation polarizability (Delta f) and E-T (30) polarity solvent parameter. The ground and excited state dipole moments were determined by applying Bakshiev’s and Kawaski-Charnma-Viallet’s formulations. Furthermore, the spectroscopic properties of thin films and powders of BTD dyes were explored. (C) 2020 Elsevier B.V. All rights reserved.

Synthesis and DSSC application of triazole bridged dendrimers with benzoheterazole surface groups

Triazole bridged dendrimers with benzoheterazole surface groups were successfully synthesized in high yields by click chemistry via convergent approach. The photophysical properties of the dendrimers reveal that as the generation increases the light absorption ability also increases. The fluorescence intensity gradually decreases as the dendritic generation increases because of fluorescence quenching due to steric crowding of the dendritic arms. On increasing the number of benzoheterazole unit at periphery, the anodic peak was shifted to higher positive potential in cyclic voltammetry. When the synthesized triazole dendrimers are utilized as an additive in the redox couple of a DSSC, the lower generation dendrimers showed better current generating capacity with higher power conversion efficiency than the higher generation dendrimers.

Design, synthesis and biological evaluation of a series of CNS penetrant HDAC inhibitors structurally derived from amyloid-beta probes

To develop novel CNS penetrant HDAC inhibitors, a new series of HDAC inhibitors having benzoheterocycle were designed, synthesized, and biologically evaluated. Among the synthesized compounds, benzothiazole derivative 9b exhibited a remarkable anti-proliferative activity (GI(50) = 2.01 mu M) against SH-SY5Y cancer cell line in a dose and time-dependent manner, better than the reference drug SAHA (GI(50) = 2.90 mu M). Moreover, compound 9b effectively promoted the accumulation of acetylated Histone H3 and alpha-tubulin through inhibition of HDAC1 and HDAC6 enzymes, respectively. HDAC enzyme assay also confirmed that compound 9b efficiently inhibited HDAC1 and HDAC6 isoforms with IC50 values of 84.9 nM and 95.9 nM. Furthermore, compound 9b inhibited colony formation capacity of SH-SY5Y cells, which is considered a hallmark of cell carcinogenesis and metastatic potential. The theoretical prediction, in vitro PAMPA-BBB assay, and in vivo brain pharmacokinetic studies confirmed that compound 9b had much higher BBB permeability than SAHA. In silico docking study demonstrated that compound 9b fitted in the substrate binding pocket of HDAC1 and HDAC6. Taken together, compound 9b provided a novel scaffold for developing CNS penetrant HDAC inhibitors and therapeutic potential for CNS-related diseases.

Benzimidazole bearing Pd-PEPPSI complexes catalyzed direct C2-arylation/heteroarylation ofN-substituted benzimidazoles

A convenient and highly efficient palladium-catalyzed direct C2-arylation/heteroarylation ofN-substituted benzimidazole derivatives such asN-benzyl/3-chlorobenzyl/2,4,6-trimethylbenzyl/2,4,6-triisopropylbenzyl/aryl benzimidazoles with various aryl/heteroaryl bromides in the presence of Pd-PEPPSI (palladium-pyridine enhanced pre-catalyst preparation stabilization and initiation) complexes is reported. In order to that we have prepared a series of different symmetrical and unsymmetricalN,N ‘-diaralkyl benzimidazole-bearing Pd-PEPPSI complexes. Among all of the the prepared complexes, Pd-PEPPSI-3effectively tuned the reaction at a relatively higher rate under mild reaction conditions in an ethanol-water system. In addition, the catalytic process avoids the use of external ligand and additives. Further the reactivity was compared with commercially available copper-N-heterocyclic carbene catalyst, but the reaction was less successful. With the optimized reaction conditions, a wide range of 2-aryl/heteroaryl-N-substituted benzimidazoles were synthesized in good to excellent yields via Csp(2)-H/Csp(2)-X biaryl cross-coupling.

A novel series of benzoxazole linked combretastatin derivatives (11a-11n) have been synthesized and confirmed by H-1 NMR, C-13 NMR, and Mass spectral analysis. The synthesized compounds (11a-11n) were screened for anticancer activity against three human cancer cell lines, Breast (MCF-7), Lung (A549), and Melanoma (A375). Most of the compounds exhibit moderate to potent anticancer activity. Among the compounds, 11g, 11h, 11l, 11m, and 11n showed more potent activity than the positive control Doxorubicin. In addition, compounds 11g, 11l, 11m, and 11n were carried out their molecular docking studies on EGFR receptor (PDB ID: 4hjo) and results indicated that 11g and 11l have strong binding interactions with the receptor. It was found that the binding energy calculations were in good agreement with the observed IC50 values.

Benzimidazole and Benzoxazole Zinc Chelators as Inhibitors of Metallo-beta-Lactamase NDM-1

Bacterial expression of beta-lactamases, which hydrolyze beta-lactam antibiotics, contributes to the growing threat of antibacterial drug resistance. Metallo-beta-lactamases, such as NDM-1, use catalytic zinc ions in their active sites and hydrolyze nearly all clinically available beta-lactam antibiotics. Inhibitors of metallo-beta-lactamases are urgently needed to overcome this resistance mechanism. Zinc-binding compounds are promising leads for inhibitor development, as many NDM-1 inhibitors contain zinc-binding pharmacophores. Here, we evaluated 13 chelating agents containing benzimidazole and benzoxazole scaffolds as NDM-1 inhibitors. Six of the compounds showed potent inhibitory activity with IC50 values as low as 0.38 mu M, and several compounds restored the meropenem susceptibility of NDM-1-expressing E. coli. Spectroscopic and docking studies suggest ternary complex formation as the mechanism of inhibition, making these compounds promising for development as NDM-1 inhibitors.

Also, (E)-2-(5-(benzo[d][1,3]dioxol-5-yl)-3-(naphthalen-1-yl)-4,5 dihydro-1H-pyrazol-1-yl)-4-methyl-5-(substituted phenyldiazenyl)thiazole (11) were prepared through reactions of carbothioamide (5a,b) with hydrazonoyl halides. In addition, thioamides (5a-b) were used as starting materials for preparation of thiazoles (12a-b) and benzylidene thiazoles (13a-b). Most of synthesized compounds show interesting biological properties as antimicrobial and antiproliferative activities, the results of minimum inhibitory concentration showed that pyrazole derivative 7c (MIC: 0.23 mg/mL) showed better results when compared with 11c and 12a (MIC: 0.1-0.125 mg/mL) as obtained from their MIC values. On the other hand, 2-(5-(benzo[d][1,3]dioxol-5-yl)-3-(naphthalen-2-yl)-4,5-dihydro-1H-pyrazol-1-yl)-4-(4-chlorophenyl) thiazole (7c) can be considered as the most promising anti-proliferative agent against HCT-116 cancer cells owing to its notable inhibitory effect on HCT-116 cells with an IC50 value of 6.19 mu M.

Synthetic transformations and biological screening of benzoxazole derivatives: A review

The presence of benzoxazole moiety in most of the heterocyclic compounds is well reported. The present literature review mainly highlights the novel synthetic transformation and describes the biological potential of most of the heterocyclic compounds by virtue of presence of benzoxazole framework. Most of the researchers have revealed that benzoxazole derivatives exhibit significant antibacterial, anti-inflammatory, antifungal, anticancer, analgesic, antiviral, anti-tubercular, and anthelmintic activities. Benzoxazole moieties also act as tyrosinase inhibitor and cholesterol ester transfer protein inhibitor. This literature review may provide an opportunity to the chemists to design new derivatives of benzoxazole that proved to be the successful agent in view of safety, effectiveness, and efficacy.

Synthesis and mesomorphic properties of benzoxazole derivatives with lateral multifluoro substituents

Fluorinated aromatics is generally chosen as mesogenic cores to design novel liquid crystal compounds. Here, a series of benzoxazole derivatives with laterally multifluorinated biphenyl units, 2-(3 ‘,3-difluoro -4 ‘-alkoxy-1,1 ‘-biphenyl-4-yl)-benzoxazole derivatives (coded as nPF(3)PF(3)Bx), are synthesized and characterized, where methyl and nitro moieties are selected as terminal groups to investigate the effects of different polar substituents on the liquid crystal properties. The compounds nPF(3)PF(3)Bx show enantiotropic mesophases with mesophase ranges of 0-40 degrees C and 0-63 degrees C on heating and cooling for hydrogen-terminated derivatives (nPF(3)PF(3)BH), 43-93 degrees C and 54-123 degrees C for methyl-terminated ones (nPF(3)PF(3)BM), 60-108 degrees C and 74-152 degrees C for nitro terminated ones (nPF(3)PF(3)BN), respectively. They exhibit photoluminescence emission peaks at 390-392 nm and UV-vis absorption bands with maxima at 327-330 nm, respectively. The results reveal that lateral multifluoro substituents lead to a decrease in melting/clearing points, while electron-withdrawing terminal nitro moiety results in increases in both melting point and mesophase range.
