Discovery of novel small molecule orally bioavailable C-X-C chemokine receptor 4 antagonists that are potent inhibitors of T-tropic (X4) HIV-1 replication

The redesign of azamacrocyclic CXCR4 chemokine receptor antagonists resulted in the discovery of novel, small molecule, orally bioavailable compounds that retained T-tropic (CXCR4 using, X4) anti-HIV-1 activity. A structure-activity relationship (SAR) was determined on the basis of the inhibition of replication of X4 HIV-1 NL4.3 in MT-4 cells. As a result of lead optimization, we identified (S)-N?-((1H-benzo[d]imidazol-2-yl)methyl)- N?-(5,6,7,8-tetrahydroquinolin-8-yl)butane-1,4-diamine (AMD070) 2 as a potent and selective antagonist of CXCR4 with an IC50 value of 13 nM in a CXCR4 125I-SDF inhibition binding assay. Compound 2 inhibited the replication of T-tropic HIV-1 (NL4.3 strain) in MT-4 cells and PBMCs with an IC50 of 2 and 26 nM, respectively, while remaining noncytotoxic to cells at concentrations exceeding 23 muM. The pharmacokinetics of 2 was evaluated in rat and dog, and good oral bioavailability was observed in both species. This compound represents the first small molecule orally bioavailable CXCR4 antagonist that was developed for the treatment of HIV-1 infection.

Synthesis of some novel benzoxazolinonylcarboxamides as potential anti-inflammatory agents

The synthesis of new 2(3H )-benzoxazolinonylcarboxamides starting from 2-amino-4,6-dimethylpyridine and 2(3H )-benzoxazolone which were designed as anti-inflammatory agents is described. These derivatives were synthesised from 2(3H )-(benzoxazolinon-6-yl)carboxylic acids, which were obtained by Friedel-Crafts acylation of 2(3H )-benzoxazolone derivatives with oxalyl chloride and acetylchloride in the presence of the AlCl3-DMF complex. The constitution of the products was supported by elemental analysis IR and 1H NMR spectral data.

Design, synthesis and pharmacology of aortic-selective acyl-CoA: Cholesterol O-acyltransferase (ACAT/SOAT) inhibitors

We describe our molecular design of aortic-selective acyl-coenzyme A:cholesterol O-acyltransferase (ACAT, also abbreviated as SOAT) inhibitors, their structure?activity relationships (SARs) and their pharmacokinetic (PK) and pharmacological profiles. The connection of two weak ligands?N-(2,6-diisopropylphenyl)acetamide (50% inhibitory concentration [IC50] = 8.6 muM) and 2-(methylthio)benzo[d]oxazole (IC50 = 31 muM)?via a linker comprising a 6 methylene group chains yielded a highly potent molecule, 9-(benzo[d]oxazol-2-ylthio)-N-(2,6-diisopropylphenyl)nonanamide (3h) that exhibited high potency (IC50 = 0.004 muM) toward aortic ACAT. This head-to-tail design made it possible to markedly enhance the activity to 2150- to 7750-fold and to discriminate the isoform-selectivity based on the double-induced fit mechanism. At doses of 1 and 3 mg/kg, 3h significantly decreased the lipid-accumulation areas in the aortic arch to 74 and 69%, respectively without reducing the plasma total cholesterol level in high fat- and cholesterol-fed F1B hamsters. Here, we demonstrate the antiatherosclerotic effect of 3h in vivo via its direct action on aortic ACAT and its powerful modulator of cholesterol level. This molecule is a potential therapeutic agent for the treatment of diseases involving ACAT-1 overexpression.

Antimalarials. Synthesis and antimalarial activity of 1 (4 methoxycinnamoyl) 4 (5 phenyl 4 oxo 2 oxazolin 2 yl)piperazine and derivatives

The preparation and activity against Plasmodium berghei of derivatives of 1 (4 methoxycinnamoyl) 4 (5 phenyl 4 oxo 2 oxazolin 2 yl)piperazine are described. Replacement of the cinnamoyl group was accomplished by acylation or alkylation of 1 (5 phenyl 4 oxo 2 oxazolin 2 yl)piperazine. Modifications of the 5 phenyl group were prepared either by a sequence of reactions involving mandelic ester pemoline piperazine pemoline or by the reaction of 5 aryl 2 thio 2,4 oxazolidinedione with piperazine or N substituted piperazines. In a similar manner, pemoline was allowed to react with N arylpiperazine, hexahydro 1H 1,4 diazepine, and 2,6 dimethylpiperazine to provide N arylpiperazine pemoline derivatives and variations in the piperazine moiety. Several compounds in which the 2 oxazolin 4 one ring was replaced with other heterocyclic rings were prepared as were several open chain analogs. Five compounds (three of them substituted in the para position of the 5 phenyl group and two N arylpiperazine pemoline derivatives) were found to be active against Plasmodium berghei. The remaining active compound possessed changes in the cinnamoyl group and substitution on the 5 phenyl group.

Biomimetic Synthesis of 4-Acetylbenzoxazolin-2(3H)-one Isolated from Zea mays

4-Acctylbenzoxazolin-2(3H)-one has been prepared biomimetically during attempts to synthesize the hemiacetalic hydroxamic acid 5-acetyl-2,4-dihydroxy-2H-1,4-benzoxazin-3(4H)-one by the immediate degradation of this unstable compound generated as an intermediate. Thus, 4-acetylbenzoxazolin-2(3H)one recently isolated from Zea mays kernels, and similar to other benzoxazolin-2(3H)-ones known from plant sources, is assumed to have originated from the degradation of natural 5-acetyl-2,4-dihydroxy-2H-1,4-benzoxazin-3(4H)-one which in turn could have been enzymatically released by a beta-glucosidase from the corresponding 2-beta-D-glucoside.

Metabolic characterization of cell systems used in in vitro toxicology testing: Lung cell system BEAS-2B as a working example

The bioactivation of pro-toxicants is the biological process through which some chemicals are metabolized into reactive metabolites. Therefore, in vitro toxicological evaluation should ideally be conducted in cell systems retaining adequate metabolic competency and relevant to the route of exposure. The respiratory tract is the primary route of exposure to inhaled pro-toxicants and lung-derived BEAS-2B cell line has been considered as a potentially suitable model for in vitro toxicology testing. However, its metabolic activity has not been characterized.We performed a gene expression analysis for 41 metabolism-related genes and compared the profile with liver- and lung-derived cell lines (HepaRG, HepG2 and A549). To confirm that mRNA expression was associated with the corresponding enzyme activity, we used a series of metabolic substrates of CYPs (CYP1A1/1B1, CYP1A2, CYP2A6/2A13 and CYP2E1) known to bioactivate inhaled pro-toxicants. CYP activities were compared between BEAS-2B, HepaRG, HepG2, and A549 cells and published literature on primary bronchial epithelium cells (HBEC).We found that in contrast to HBEC, BEAS-2B and A549 have limited CYP activity which was in agreement with their CYP gene expression profile. Control cell lines such as HepG2 and HepaRG were metabolically active for the tested CYPs. We recommend that similar strategies can be used to select suitable cell systems in the context of pro-toxicant assessment.

Mass spectra of halogenostyrylbenzoxazoles

Several series of styrylbenzoxazoles of general formula XC 6H3(NCO)CHCHC6H4Y [X = F, Cl or Br; Y = H, F, Cl, Br, CH3 or CH3O] have been investigated by positive ion electrospray and electron ionization mass spectrometry. These compounds, many of which are biologically active or have pharmaceutical potential, show in their electrospray spectra strong peaks for MH+ ions, which undergo relatively little fragmentation. The electron ionization spectra are extremely clean, being dominated by the loss of an atom or radical, Y, from the ortho position of the pendant ring, by a rearrangement that may be interpreted as a proximity effect. The resultant [M-Y]+ ions are exceptionally stable and rarely undergo further fragmentation. The analytical value of this proximity effect, which is analogous to intramolecular aromatic substitution, in revealing the presence of a substituent in the pendant ring and determining its position, is emphasized. Elimination of a species (including H or F) derived from an ortho substituent in the pendant ring occurs even when apparently more favourable alternative fragmentation is possible by direct cleavage of the CX bond (X = Cl or Br) in the benzoxazole ring.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: C8H6FNO, you can also check out more blogs about701-16-6

In vitro evaluation of potential drug interactions mediated by cytochrome P450 and transporters for luseogliflozin, an SGLT2 inhibitor

1. We evaluated potential in vitro drug interactions of luseogliflozin, a sodium-glucose cotransporter 2 (SGLT2) inhibitor, mediated by CYP inhibition, CYP induction and drug transporters using human liver microsomes, primary hepatocytes and recombinant cells-expressing efflux or uptake transporters, respectively. 2. Human CYP inhibition studies indicated that luseogliflozin was a weak inhibitor for CYP2C19 with an IC50 value of 58.3 muM, whereas it was not an inhibitor of the other eight major isoforms that were tested. The exposure of primary hepatocytes to luseogliflozin for 72 hrs weakly induced CYP3A4 at a concentration of 10 muM, whereas it did not induce CYP1A2 or CYP2B6 at concentrations of 0.1?10 muM. 3. An in vitro transport study suggested that luseogliflozin is a substrate for human P-glycoprotein (P-gp), but not for breast cancer resistance protein (BCRP), organic anion transporting polypeptide (OATP) 1B1 and OATP1B3, organic anion transporter (OAT) 1 and OAT3, or organic cation transporter (OCT) 2. Luseogliflozin weakly inhibited OATP1B3 with an IC50 value of 93.1 muM, but those for other transporters are greater than 100 muM. 4. Based on the therapeutic plasma concentration of the drug, clinically relevant drug interactions are unlikely to occur between luseogliflozin and coadministered drugs mediated by CYPs and/or transporters.

Nickel-catalyzed decarboxylative arylation of heteroarenes through sp2 C-H functionalization

The direct decarboxylative arylation of hetereoarenes with benzoic acids through a nickel-catalyzed sp2 C-H functionalization process was developed. This process provides the first examples of decarboxylative cross-coupling reactions with aromatic acids through nickel catalysis and tolerates a variety of functional groups. Moreover, this method provides efficient access to 2-aryl-substituted azoles, an important structural unit in natural products, medicinal compounds, and functional materials.

Design and synthesis of novel benzo[ d[oxazol-2(3H)-one derivatives bearing 7-substituted-4-enthoxyquinoline moieties as c-Met kinase inhibitors

Analysis of the results of studies of docking 1 and 7a with c-Met kinase led to the identification of benzo [d]oxazol-2(3H)-one-quinolone derivatives as potential inhibitors of this enzyme. A molecular hybrid strategy, using a 4-ethoxy-7-substituted-quinoline core and a benzo[d]oxazol-2(3H)-one scaffold, was employed to design members of this family for study as inhibitors of the kinase and proliferation of EBC-1 cells. Most of the substances were found to display good to excellent c-Met kinase inhibitory activities. The results of a structureeactivity relationship (SAR) study led to the discovery of benzo[d]oxazol-2(3H)-one-quinolone 13, which has IC50 values of 1 nM against c-Met kinase and 5 nM against proliferation of the EBC-1 cell line.
