Liu, Zheng published the artcileC-3 benzoic acid derivatives of C-3 deoxybetulinic acid and deoxybetulin as HIV-1 maturation inhibitors, Application In Synthesis of 724710-02-5, the publication is Bioorganic & Medicinal Chemistry (2016), 24(8), 1757-1770, database is CAplus and MEDLINE.

A series of C-3 phenyl- and heterocycle-substituted derivatives of C-3 deoxybetulinic acid and C-3 deoxybetulin was designed and synthesized as HIV-1 maturation inhibitors (MIs) and evaluated for their antiviral activity and cytotoxicity in cell culture. A 4-subsituted benzoic acid moiety was identified as an advantageous replacement for the 3’3′-dimethylsuccinate moiety present in previously disclosed MIs that illuminates new aspects of the topog. of the pharmacophore. The new analogs exhibit excellent in vitro antiviral activity against wild-type (wt) virus and a lower serum shift when compared with the prototypical HIV-1 MI bevirimat (1, BVM), the first MI to be evaluated in clin. studies. Compound 9a exhibits comparable cell culture potency toward wt virus as 1 (WT EC₅₀ = 16 nM for 9a compared to 10 nM for 1). However, the potency of 9a is less affected by the presence of human serum, while the compound displays a similar pharmacokinetic profile in rats to 1. Hence 9a, the 4-benzoic acid derivative of deoxybetulinic acid, represents a new starting point from which to explore the design of a 2nd generation MI.

As a part of our continuous structure-activity relationship (SAR) studies on 1-(quinazolin-4-yl)-1-(4-methoxyphenyl)ethan-1-ols, the synthesis of derivatives and their cytotoxicity against the human lung cancer cell line A549 were explored. This led to the discovery of 1-(2-(furan-3-yl)quinazolin-4-yl)-1-(4-methoxyphenyl)ethan-1-ol (PVHD303) with potent antiproliferative activity. PVHD303 disturbed microtubule formation at the centrosomes and inhibited the growth of tumors dose-dependently in the HCT116 human colon cancer xenograft model in vivo.

Hong, Fang-Tsao published the artcileSmall Molecule Disruptors of the Glucokinase-Glucokinase Regulatory Protein Interaction: 4. Exploration of a Novel Binding Pocket, HPLC of Formula: 724710-02-5, the publication is Journal of Medicinal Chemistry (2014), 57(14), 5949-5964, database is CAplus and MEDLINE.

Structure-activity relationship investigations conducted at the 5-position of the N-pyridine ring of a series of N-arylsulfonyl-N’-2-pyridinyl-piperazines led to the identification of a novel bis-pyridinyl piperazine sulfonamide I that was a potent disruptor of the glucokinase-glucokinase regulatory protein (GK-GKRP) interaction. Anal. of the x-ray cocrystal of compound I bound to hGKRP revealed that the 3-pyridine ring moiety occupied a previously unexplored binding pocket within the protein. Key features of this new binding mode included forming favorable contacts with the top face of the Ala27-Val28-Pro29 (“shelf region”) as well as an edge-to-face interaction with the Tyr24 side chain. Compound I was potent in both biochem. and cellular assays (IC₅₀ = 0.005 μM and EC₅₀ = 0.205 μM, resp.) and exhibited acceptable pharmacokinetic properties for in vivo evaluation. When administered to db/db mice (100 mg/kg, po), compound I demonstrated a robust pharmacodynamic effect and significantly reduced blood glucose levels up to 6 h postdose.

Desroy, Nicolas published the artcileTowards Gram-negative antivirulence drugs: New inhibitors of HldE kinase, Safety of (1H-Pyrazol-5-yl)boronic acid, the publication is Bioorganic & Medicinal Chemistry (2009), 17(3), 1276-1289, database is CAplus and MEDLINE.

Gram-neg. bacteria lacking heptoses in their lipopolysaccharide (LPS) display attenuated virulence and increased sensitivity to human serum and to some antibiotics. Thus inhibition of bacterial heptose synthesis represents an attractive target for the development of new antibacterial agents. HldE is a bifunctional enzyme involved in the synthesis of bacterial heptoses. Development of a biochem. assay suitable for high-throughput screening allowed the discovery of inhibitors 1 and 2 of HldE kinase. Study of the structure-activity relation of this series of inhibitors led to highly potent compounds

Wu, Yuchuan published the artcileDiscovery of potent and selective matrix metalloprotease 12 inhibitors for the potential treatment of chronic obstructive pulmonary disease (COPD), Product Details of C3H5BN2O2, the publication is Bioorganic & Medicinal Chemistry Letters (2012), 22(1), 138-143, database is CAplus and MEDLINE.

Chronic obstructive pulmonary disease (COPD) is an inflammatory lung disease associated with irreversible progressive airflow limitation. Matrix metalloproteinase-12 (MMP-12) has been characterized to be one of the major proteolytic enzymes to induce airway remodeling, destruction of elastin and the aberrant remodeling of damaged alveoli in COPD and asthma. The goal of this project is to develop and identify an orally potent and selective small mol. inhibitor of MMP-12 for treatment of COPD and asthma. Syntheses and structure-activity relationship (SAR) studies of a series of dibenzofuran (DBF) sulfonamides as MMP-12 inhibitors are described. Potent inhibitors of MMP-12 with excellent selectivity against other MMPs were identified. Compound I (MMP118), which exhibits excellent oral efficacy in the MMP-12 induced ear-swelling inflammation and lung inflammation mouse models, had been successfully advanced into Development Track status.
