Identification of a Novel Class of BRD4 Inhibitors by Computational Screening and Binding Simulations

Computational screening is a method to prioritize small-molecule compounds based on the structural and biochemical attributes built from ligand and target information. Previously, we have developed a scalable virtual screening workflow to identify novel multitarget kinase/bromodomain inhibitors. In the current study, we identified several novel N-[3-(2-oxo-pyrrolidinyl)phenyl]-benzenesulfonamide derivatives that scored highly in our ensemble docking protocol. We quantified the binding affinity of these compounds for BRD4(BD1) biochemically and generated cocrystal structures, which were deposited in the Protein Data Bank. As the docking poses obtained in the virtual screening pipeline did not align with the experimental cocrystal structures, we evaluated the predictions of their precise binding modes by performing molecular dynamics (MD) simulations. The MD simulations closely reproduced the experimentally observed protein-ligand cocrystal binding conformations and interactions for all compounds. These results suggest a computational workflow to generate experimental-quality protein-ligand binding models, overcoming limitations of docking results due to receptor flexibility and incomplete sampling, as a useful starting point for the structure-based lead optimization of novel BRD4(BD1) inhibitors.

Process Research and Development of an Enantiomerically Enriched Allyic Amine, One of the Key Intermediates for the Manufacture of Synthetic Tetracyclines

A robust, cost-effective, and high yielding manufacturing process for enantiomerically enriched (S)-allylic amine 3, a key intermediate for fully synthetic tetracyclines have been developed. Two novel and scalable asymmetric vinylations resulting in high-to-excellent stereoselectivity have been developed for the key step. The final product is purified by an efficient crystallization of a l-tartaric salt. The process described has been used to manufacture ?350 kg of the tartaric salt of 3 with 99.0% ee in 8 steps (35% overall yield) from cheap and readily available dimethyl maleate.

Some Heterocyclic Sulfonyl Chlorides and Derivatives

The syntheses of 4- and 5-chlorosulfonylfuran-2-carboxylic acid (Ia,IIa), 4-chlorosulfonylfuran-2-carboxamide (Ib), 3,5-dimethylpyrazole and isoxazole-4-sulfonyl chlorides (IIa, IVa) and 2,4-dimethylthiazole-5-sulfonyl chloride (Va) are described.The sulfonyl chlorides were converted into a range of amides, hydrazides and azides.Condensation of the sulfonohydrazides with beta-dicarbonyl compounds, gave the corresponding beta-ketohydrazones (VII), which, with the exeption of the derivatives (VIIe,f,g,i), were converted to the sulfonylpyrazoles (VIII).The structures and spectral data of these compounds are briefly discussed.The reactio n of the sodio derivative of acetylacetone with thiophene-2-sulfonyl chloride (VIc) gave 3-(thiophene-2-sulfonyl)pentane-2,4-dione (XII), which with hydrazine gave 4-(thiophene-2-sulfonyl)-3,5-dimethylpyrazole (XIII).However, the analogous reaction with thiophene-2-sulphonohydrazide (VIa) failed to give the expected 1,4-bisthiophenesulfonylpyrazole.

An unexpected mechanism of action of the styrene polymerisation retarder 2,4-dinitro-6-sec-butylphenol

The reaction of ‘DNBP’ (2,4-dinitro-6-sec-butylphenol) with toluene, ethylbenzene or styrene and tert-butylperoxide at 110C leads to 7-sec-butyl-5-nitro-2-phenylbenzoxazole. This benzoxazole was also detected in the residues of an industrial styrene fractionation still in which DNBP was routinely used as the polymerisation retarder. The formation of this product from either ethyl benzene or from styrene involves a carbon-carbon bond cleavage step.

Synthesis of isoxazole moiety containing ferrocene derivatives and preliminarily in vitro anticancer activity

Seven new structures of an isoxazole moiety containing ferrocene derivatives (3a-3g) were firstly synthesized and characterized by 1H NMR, 13C NMR, ESI-MS. Subsequently, their in vitro anticancer activity against A549, HCT116 and MCF-7 cell lines was preliminarily evaluated using the MTT method. Among them, 3d exhibited a wide spectrum and the most potent anticancer activity against A549 and HCT116 cell lines (IC50s: 0.747 and 3.65 nM, respectively) as compared with the reference drug gefitinib (IC50s: 17.90 and 21.55 muM, respectively). 3d can be seen as the best candidate for development of anticancer drugs.

Efficient bulk scale synthesis of popular pesticide synthon: tetrachlorothiophene

Broad spectrum pesticides are molecules which act across a range of pests. The popular class of compounds with this property are thiacloprid, nitenpyram, ethaboxam, silthiofam, 3,3,4,4-tetrachloro tetrahydro thiophene etc. Interestingly, all these compounds possess at least one heterocyclic ring like thiophene, furan, and imidazole etc. in their structure. Among the synthons available for synthesis of neonicotinoids, tetrachlorothiophene is unique. The bulk scale synthesis of tetrachlorothiophene is reported only by cyclization of hexachloro-1,3-butadiene. The reaction yields of synthesis of this synthon are around 45%. We report silica-coated magnetic nanoparticles as a generic catalyst for this cyclization reaction yielding tetrachlorothiophene. The yield improvement is 50?60% more compared to original yield. The distillate crystallization in methanol yielded?>98% pure compound compared to typical 90?92% in conventional process. The proposed reaction uses reusable silica-coated 40?nm size magnetic nanoparticles and the catalyst itself is of low cost and reaction conditions are mild.
