The bromodomain containing proteins TRIM24 (tripartite motif containing protein 24) and BRPF1 (bromodomain and PHD finger containing protein 1) are involved in the epigenetic regulation of gene expression and have been implicated in human cancer. Overexpression of TRIM24 correlates with poor patient prognosis, and BRPF1 is a scaffolding protein required for the assembly of histone acetyltransferase complexes, where the gene of MOZ (monocytic leukemia zinc finger protein) was first identified as a recurrent fusion partner in leukemia patients (8p11 chromosomal rearrangements). Here, we present the structure guided development of a series of N,N-dimethylbenzimidazolone bromodomain inhibitors through the iterative use of X-ray cocrystal structures. A unique binding mode enabled the design of a potent and selective inhibitor 8i (IACS-9571) with low nanomolar affinities for TRIM24 and BRPF1 (ITC Kd = 31 nM and ITC Kd = 14 nM, respectively). With its excellent cellular potency (EC50 = 50 nM) and favorable pharmacokinetic properties (F = 29%), 8i is a high-quality chemical probe for the evaluation of TRIM24 and/or BRPF1 bromodomain function in vitro and in vivo.

An efficient pyridyl-directed Rh(III)-catalyzed o-carborane B(3)-H acyloxylation is reported. The B(3)-H bond is the most electron-deficient vertex on o-carborane whose functionalization is challenging. The combination of Cu(OH)2 and diverse carboxylic acids provides low cost and abundant acyloxyl sources which could lead to moderate to excellent yields.

Poly (3-hydroxybutyrate) (PHB) is a naturally occurring biodegradable and biocompatible polyester and considered as a class of potentially thermoplastic biopolymers in industry. The alternating copolymerization of cheap and available propylene oxide and carbon monoxide may be an efficient synthetic route for PHB. Here, we studied the base effects on the synthesis of PHB using a well-defined [(salph)Cr(THF)2]+[Co(CO)4]? catalyst combined with various bases. It was found that base not only affects the yield of PHB, but also the molar ratio of each unit in the product.

Several series of 2,4-dihydro-2,4,5-trisubstituted-3H-1,2,4-triazol-3-ones with acidic sulfonamide replacements of tetrazole at the 2′-position of the biphenyl-4-ylmethyl side chain at N4 were prepared and tested as angiotensin II (AII) antagonists.Preferred substituents on the triazolinone ring were n-butyl at C5 and 2-(trifluoromethyl)phenyl at N2.Subnanomolar IC50 values at the AT1 receptor subtype were observed for a variety of acylsulfonamides, including aroyl, heteroaroyl, and cycloalkylcarbonyl derivatives.Certain other acidic sulfonamides, such as sulfonylcarbamates and disulfimides also displayed high affinity for the AT1 receptor.In addition, AT2 binding for some of these compounds was increased by as much as 1000-fold over the corresponding tetrazole (e.g., AT2 IC50 17 nM for the tert-butyl sulfonylcarbamate 92).When evaluated for inhibition of the AII pressor response, the benchmark benzoylsulfonamide 9 (L-159,913) was efficacious in several species and was superior to losartan (1a) in conscious rhesus monkeys.Several subsequent analogues, including the 2-chlorobenzoyl (18), (3-chlorothiophene-2-yl)carbonyl (51), ((S)-2,2-dimethylcyclopropyl)carbonyl (80), and tert-butoxycarbonyl (92) derivatives, were highly effective in rats, surpassing 9 and losartan in duration of action and/or potency.Compound 18 (L-162,223) displayed very prolonged AII antagonism in the rat model (>24 h at 1 mg/kg iv).At 1 mg/kg po in rats, 18 and 92 (L-162,234) produced 85-87percent peak inhibition of the AII pressor response with duration exceeding 6 h.The identification of triazolinone-based sulfonamide derivatives combining high AT1 affinity, considerably enhanced AT2 potency, and favorable in vivo properties provides insights relevant to the design of dual AT1/AT2 receptor antagonists.

A series of 11-aryl-8,11-dihydrofuro[3′,4′:5,6]pyrido[3,2-f]quinoxalin-10(7H)-one derivatives were obtained via a one-pot and three-component reaction of aromatic aldehydes, 6-aminoquinoxaline and tetronic acid in EtOH. The structure of 11-(4-nitrophenyl)-8,11-dihydrofuro[3′,4′:5,6]pyrido[3,2-f]quinoxalin-10(7H)-one (4g) was confirmed by X-ray diffraction analysis. This procedure had the advantages of operation simplicity, catalyst-free and without isolating intermediates, and provided a good method for the synthesis of fused tetracyclic heterocycles containing furan, pyridine and quinoxaline moieties at the same time.

An electrocatalytic method has been developed to oxidize primary alcohols and aldehydes to the corresponding carboxylic acids using 4-acetamido-2,2,6,6-tetramethylpiperidin-1-oxyl (ACT) as a mediator. The method successfully converts benzylic, aliphatic, heterocyclic, and other heteroatom-containing substrates to the corresponding carboxylic acids in aqueous solution at room temperature. The mild conditions enable retention of stereochemistry adjacent to the site of oxidation, as demonstrated in a 40 g-scale synthesis of a precursor to levetiracetam, a medication used to treat epilepsy.

The first catalytic method for the efficient conversion of epoxides to succinic anhydrides via one-pot double carbonylation is reported. This reaction occurs in two stages: first, the epoxide is carbonylated to a beta-lactone, and then the beta-lactone is subsequently carbonylated to a succinic anhydride. This reaction is made possible by the bimetallic catalyst [(CITPP)Al(THF)2]+[Co(CO)4]- (1; CITPP = meso-tetra(4-chlorophenyl)porphyrinato; THF = tetrahydrofuran), which is highly active and selective for both epoxide and lactone carbonylation, and by the identification of a solvent that facilitates both stages. The catalysis is compatible with substituted epoxides having aliphatic, aromatic, alkene, ether, ester, alcohol, nitrile, and amide functional groups. Disubstituted and enantiomerically pure anhydrides are synthesized from epoxides with excellent retention of stereochemical purity. The mechanism of epoxide double carbonylation with 1 was investigated by in situ IR spectroscopy, which reveals that the two carbonylation stages are sequential and non-overlapping, such that epoxide carbonylation goes to completion before any of the intermediate beta-lactone is consumed. The rates of both epoxide and lactone carbonylation are independent of carbon monoxide pressure and are first-order in the concentration of 1. The stages differ in that the rate of epoxide carbonylation is independent of substrate concentration and first-order in donor solvent, whereas the rate of lactone carbonylation is first-order in lactone and inversely dependent on the concentration of donor solvent. The opposite solvent effects and substrate order for these two stages are rationalized in terms of different resting states and rate-determining steps for each carbonylation reaction.
