Hydroxynitrile lyase (HNL) catalyzed enantioselective C-C bond formation is an efficient approach to synthesize chiral cyanohydrins which are important building blocks in the synthesis of a number of fine chemicals, agrochemicals and pharmaceuticals. Immobilization of HNL is known to provide robustness, reusability and in some cases also enhances activity and selectivity. We optimized the preparation of immobilization of Baliospermium montanum HNL (BmHNL) by cross linking enzyme aggregate (CLEA) method and characterized it by SEM. Optimization of biocatalytic parameters was performed to obtain highest % conversion and ee of (S)-mandelonitrile from benzaldehyde using CLEA-BmHNL. The optimized reaction parameters were: 20 min of reaction time, 7 U of CLEA-BmHNL, 1.2 mM substrate, and 300 mM citrate buffer pH 4.2, that synthesized (S)-mandelonitrile in 99% ee and 60% conversion. Addition of organic solvent in CLEA-BmHNL biocatalysis did not improve in % ee or conversion of product unlike other CLEA-HNLs. CLEA-BmHNL could be successfully reused for eight consecutive cycles without loss of conversion or product formation and five cycles with a little loss in enantioselectivity. Eleven different chiral cyanohydrins were synthesized under optimal biocatalytic conditions in up to 99% ee and 59% conversion, however the % conversion and ee varied for different products. CLEA-BmHNL has improved the enantioselectivity of (S)mandelonitrile synthesis compared to the use of purified BmHNL. Nine aldehydes not tested earlier with BmHNL were converted into their corresponding (S)-cyanohydrins for the first time using CLEA-BmHNL. Among the eleven (S)-cyanohydrins syntheses reported here, eight of them have not been synthesized by any CLEA-HNL. Overall, this study showed preparation, characterization of a stable, robust and recyclable biocatalyst i.e. CLEA-BmHNL and its biocatalytic application in the synthesis of different (S)-aromatic cyanohydrins.

Here, we have established a new and simple synthetic approach to the pentacycloundecane containing cage oxazole unit in four steps. The synthesis begun with a cheap and readily available materials such as 2,5-dimethoxybenzaldehyde and endo-dicyclopentadiene. This approach relies on Van Leusen oxazole synthesis and [2+2] photocycloaddition as key steps. To the best of our knowledge, this is the first example of Cookson’s dione containing oxazole ring system. Some of these oxazole motifs are useful in bioorganic chemistry and our results are likely to draw the attention of medicinal chemists

Despite the fact that significant advances in treatment of common cancers have been achieved over the years, orphan tumors still represent an important unmet medical need. Due to their complex multifactorial origin and limited number of cases, such pathologies often have very limited treatment options and poor prognosis. In the search for new anticancer agents, our group recently identifiedRC-106, a Sigma receptor modulator endowed with proteasome inhibition activity. This compound showed antiproliferative activity toward different cancer cell lines, among them glioblastoma (GB) and multiple myeloma (MM), two currently unmet medical conditions. In this work, we directed our efforts toward the exploration of chemical space aroundRC-106to identify new active compounds potentially useful in cancer treatment. Thanks to a combinatorial approach, we prepared 41 derivatives of the compound and evaluated their cytotoxic potential against MM and GB. Three novel potential anticancer agents have been identified.

The Pomeranz-Fritsch reaction and its Schlittler-Muller modification were successfully applied in the Ugi postcyclization strategy by using orthogonally protected aminoacetaldehyde diethyl acetal and complementary electron rich building blocks. Several scaffolds, including isoquinolines, carboline, alkaloid-like tetrazole-fused tetracyclic compounds, and benzo[d]azepinone scaffolds, were synthesized in generally moderate to good yield. All our syntheses provide a short MCR-based sequence to novel or otherwise difficult to access scaffolds. Hence, we foresee multiple applications of these synthesis technologies.

Cyclin-dependent kinases play significant roles in cell cycle progression and are promising targets for cancer therapy. However, most potent CDK inhibitors lack the balance between efficacy and safety because of poor selectivity. Given the roles of CDK2 in tumorigenesis, selective CDK2 inhibition may provide therapeutic benefits against certain cancer. In this study, a series of 4-benzoylamino-1H-pyrazole-3-carboxamide derivatives were designed, synthesized, and evaluated. The most selective compound DC-K2in212 in this series exhibited high potency towards CDK2 and had effective anti-proliferative activity against A2058 melanoma cell line and MV4-11 leukemia cell line while exhibiting low toxic effect on human normal cell lines MRC5 and LX2. The molecular modeling illustrated that compound DC-K2in212 had the similar binding mode with CDK2 as C-73, the most selective CDK2 inhibitor reported so far, which might account for selectivity against CDK2 over CDK1. Further biological studies revealed that compound DC-K2in212 suppressed CDK2-associated downstream signaling pathway, blocked cell cycle progression, and induced cellular apoptosis. Therefore, compound DC-K2in212 could serve as a potential CDK2 inhibitor for further development. (c) 2021 Elsevier Masson SAS. All rights reserved.

A detailed structural analysis has been carried out on four chalcone (E)-1-(2-hydroxyphenyl)-3-phenylprop-2-en-1-one derivatives, having a varying number of methoxy substituents, namely (E)-3-(3,4-dimethoxyphenyl)-1-(2-hydroxyphenyl)prop-2-en-1-one, (1), (E)-3-(4-methoxyphenyl)-1-(2-hydroxy-4-methoxyphenyl)prop-2-en-1-one, 2, (E)-3-(2,5-dimethoxyphenyl)-1-(2-hydroxy-4-methoxyphenyl)prop-2-en-1-one, 3, and (E)-3-(2,5-dimethoxyphenyl)-1-(2-hydroxy-3,4-dimethoxyphenyl)prop-2-en-1-one, 4. Crystal structures were determined at 100 K by single crystal X-ray diffraction. Compound 2 displayed an unexpectedly large interplanar angle of 25 and 28(,o) between the phenyl groups in the two independent molecules, due to the formation of a dimeric substructure requiring a pronounced phenyl group rotation to minimise steric hindrance. Such a substructure was absent in 1, 3 and 4. In all cases the 2-hydroxyl substituent forms intramolecular hydrogen bonds with its neighbouring carbonyl group. Different combinations of C-H center dot center dot center dot O, C-H center dot center dot center dot pi and/or pi center dot center dot center dot pi interactions are displayed by 1, 3 and 4, with also C=O center dot center dot center dot pi intermolecular interactions present in 2. The relative contributions of various intermolecular contacts in these structures were investigated using Hirshfeld surfave analysis and the associated two dimensional fringerprint plots. Important molecule pairs were identified in the crystal structures using the PIXEL method. The PIXEL lattice energy calculations revealed that in all cases the dispersion contribution was the major contributor to the packing stabilization, followed by the Coulombic contribution. A search of structures of alkoxy derivatives of (E)-1-(2-hydroxyphenyl)-3-phenylprop-2-en-1-one derivatives in the CCDC data base has also been carried out. (C) 2020 Published by Elsevier B.V.

Chalcones are interesting candidates for anti-cancer drugs due to the ease of their synthesis and their extensive biological activity. The study presents antitumor activity of newly synthesized chalcone analogues with a methoxy group on a panel of canine lymphoma and leukemia cell lines. The antiproliferative effect of the 2 ‘-hydroxychalcone and its methoxylated derivatives was evaluated in MTT assay after 48 h of treatment in different concentrations. The proapoptotic activity was studied by cytometric analysis of cells stained with Annexin V/FITC and propidium iodide and by measure caspases 3/7 and 8 activation. The DNA damage was evaluated by Western blot analysis of phosphorylated histone H2AX. The new compounds had selective antiproliferative activity against the studied cell lines, the most effective were the 2 ‘-hydroxy-2 ”,5 ”-dimethoxychalcone and 2 ‘-hydroxy-4 ‘,6 ‘-dimethoxychalcone. 2 ‘-Hydroxychalcone and the two most active derivatives induced apoptosis and caspases participation, but some percentage of necrotic cells was also observed. Comparing phosphatidylserine externalization after treatment with the different compounds it was noted that the addition of two methoxy groups increased the proapoptotic potential. The most active compounds triggered DNA damage even in the cell lines resistant to chalcone-induced apoptosis. The results confirmed that the analogues could have anticancer potential in the treatment of canine lymphoma or leukemia.

A series of novel alpha-aminophosphonate derivatives were synthesized via simple and an efficient method from the three-component condensation reaction of 5-aminoindan or 3,4-(methylenedioxy)aniline, aromatic aldehydes and diethyl phosphite by employing graphene nanosheets-silver nanoparticles (GNS-AgNPs) as catalyst under ultrasonication and solvent-free condition. GNS-AgNPs was prepared in situ by simultaneous reduction of graphene oxide (GO) and silver nitrate (AgNO3) using sodium borohydride (NaBH4) as a reducing agent. The surface characterization of GNS-AgNPs was done using X-ray diffraction (XRD), Fourier transform infrared (FTIR), UV-Vis spectroscopy (UV-Vis), Thermogravimetric analysis (TGA), Raman spectroscopy and Field emission scanning electron microscopy (FE-SEM). The GNS-AgNPs are recyclable up to fifth run with minimal loss of its activity. Convenient operational simplicity, mild conditions, excellent yields of products, consistent performance and the reusability of catalyst makes this protocol feasible and attractive.

This study reports a simple process to synthesize and separate of 2-(substituted-phenyl) benzimidazole derivatives with high yield and efficiency. Specifically, by reacting ortho-phenylenediamines with benzaldehydes using sodium metabisulphite as an oxidation agent in a mixture of solvent under mild condition, twenty-three compounds of benzimidazoles were obtained and separated easily using hexane and water to wash, respectively. The structure of all obtained compounds was identified by FTIR, NMR and HRMS. The SAR analysis of synthesized benzimidazoles on human lung (A549), breast (MDA-MB-231) and prostate (PC3) cancer cell lines showed that the presence of methyl group at 5(6)-position on benzimidazole scaffold was a contributing factor influencing the anticancer activity. The presence of electron-donating groups (OH, OMe, -NMe2, -O-CH2-C6H5) also caused significant increase of anticancer activity, while the presence of electron-withdrawing groups (-NO2, -CF3) on the phenyl group at 2-position of benzimidazole ring decreased the ability of inhibition of synthesized benzimidazoles. The compounds 2f and 2g displayed the significant anticancer activity on both A549 and PC3 cell lines.
