Shen, Qionghua published the artcileSynthesis, Characterization, and Glass Transitions of Some Asymmetrically Substituted Poly(siloxanes), Safety of Dichloro(hexyl)(methyl)silane, the publication is Macromolecules (1997), 30(18), 5485-5489, database is CAplus.

A homologous series of poly(n-alkylmethylsiloxanes), [SiMe(R)O]_n, were prepared by cationic ring-opening polymerization (ROP) of cyclotrisiloxanes containing n-alkyl substituents, such as C₂H₅, n-C₃H₇, n-C₄H₉, n-C₅H₁₁, and n-C₆H₁₃, on the Si. The resultant polymers were characterized by NMR, GPC, and DSC measurements. All of these asym. substituted polymers were obtained in high mol. weight form and were found to have an atactic configuration. Their glass transitions were found to increase smoothly from Et to n-hexyl (i.e., -139, -120, -115, -111.9, and -108 °C, for Et to n-hexyl, resp.). These T_gs are much lower than those of the corresponding polyolefins, [C(H)(R)CH₂]_n. Moreover, in the case of these polyolefins, the T_gs decrease continuously from R = Me to n-hexyl. The calculated T_gs for the polysiloxanes that were obtained by using published empirical equations show the same general trend as the exptl. values.

Nagao, Yoshimitsu published the artcileA new nonenzymatic chiral induction into prochiral meso compounds, Related Products of chlorides-buliding-blocks, the publication is Tetrahedron (1984), 40(8), 1215-23, database is CAplus.

A highly selective asym. induction into prochiral meso compounds used the chiral methoxycarbonyl-1,3-thiazolidine-2-thione I. Thus, condensation of I with the dimethylglutaric anhydride II in CH₂Cl₂-pyridine containing DCC gave 64.1% diamide III which underwent aminolysis with piperidine to give piperidide IV. Nucleophilic substitution reactions of IV gave the chiral meso compounds V [R = Me₂S⁺(O)C^–H, EtO₂CCH₂, 4-BrC₆H₄S, PhCHMeNH] in 79.1-98.7% yields. The mol. structure of IV was confirmed by x-ray crystal structure anal.

Davis, Rohan A. published the artcileCarbonic anhydrase inhibitors. Identification of selective inhibitors of the human mitochondrial isozymes VA and VB over the cytosolic isozymes I and II from a natural product-based phenolic library, Recommanded Product: 3-Chloro-4-hydroxyphenylacetic acid, the publication is Bioorganic & Medicinal Chemistry (2010), 18(1), 14-18, database is CAplus and MEDLINE.

We have investigated the enzyme inhibition characteristics of a natural product (NP)-based phenolic library against a panel of human carbonic anhydrases (hCAs, EC 4.2.1.1) which included hCAs I and II (cytosolic) and hCA VA/VB (mitochondrial isoforms). Most of these compounds were weak, micromolar inhibitors of the two cytosolic hCAs (K _Is >10 μM) but showed good hCA VA/VB inhibitory activity with inhibition constants in the range of 70-125 nM. The selectivity ratios for inhibiting the mitochondrial over the cytosolic isoforms for these phenol derivatives were in the range of 120-3800, making them the most isoform-selective compounds for inhibiting hCA VA/VB known to date. The CA VA/VB enzymes are involved in biosynthetic processes such as gluconeogenesis, lipogenesis and ureagenesis, and no pharmacol. inhibitors with good selectivity are currently available. Thus the NP inhibitors identified during these studies are excellent leads for obtaining even more effective compounds that selectively target mitochondrial hCAs, and also have the potential to be used as tools for understanding the physiol. processes that are regulated by the two mitochondrial CA isoforms.

Diamide I, prepared by treatment of 3-methylglutaric acid with 4(R)-(methoxycarbonyl)-1,3-thiazolidine-2-thione [4(R)-MCTT] in the presence of DCC in pyridine, was subjected to aminolysis with 1 equiv of piperidine in CH₂Cl₂ at -30° to give a mixture of diastereomers II [R₂N = piperidino, R¹₂N = MCTT moiety (III)] and II (R₂N = MCTT moiety, R¹₂N = piperidino) in a 88:12 ratio. III was separated by silica gel column chromatog. and treated with various nucleophiles to give optically pure bifunctional synthons (II; R₂N and R¹₂N = nucleophilic group) in high yields. Highly selective chiral induction into cis-4-cyclohexen-1,2-ylenebis(acetic acid) was also performed. Aminolysis of IV (R₂N and R¹₂N = MCTT moiety) (V) with 1 equiv of piperidine gave 94% diastereomer IV (R₂N = piperidino, R¹₂N = MCTT moiety). Similar chiral induction into cis-cyclohexan-1,2-xylenebis(acetic acid) and aminolysis of its 4(R)-MCTT diamide (VI) with piperidine were also carried out; opposite selectivity was obtained. The conformations of V and VI in a solvent, the relationship between the susceptibility of their conformations and environmental temperature, and the diastereoselectivity of the reaction are discussed on the basis of the 400-MHz ¹H NMR spectra.

Amidrazonophenylalanine derivative LB30057 (I) was identified as a potent (K_i=0.38 nM), selective, and orally active thrombin inhibitor. As a continuation of studies into benzamidrazone-based thrombin inhibitors, we have structurally modified I by replacing the naphthyl group with a variety of hydrophobic moieties. This study led to discovery of several compounds with significantly enhanced potency in thrombin inhibition without sacrificing selectivity against trypsin and oral absorption. The highest activity was obtained with benzocycloheptyl derivative II (K_i = 0.045 nM).

The virulence factor cystic fibrosis transmembrane conductance regulator (CFTR) inhibitory factor (Cif) is secreted by Pseudomonas aeruginosa and is the founding member of a distinct class of epoxide hydrolases (EHs) that triggers the catalysis-dependent degradation of the CFTR. We describe here the development of a series of potent and selective Cif inhibitors by structure-based drug design. Initial screening revealed 1a (KB2115), a thyroid hormone analog, as a lead compound with low micromolar potency. Structural requirements for potency were systematically probed, and interactions between Cif and 1a were characterized by X-ray crystallog. On the basis of these data, new compounds were designed to yield addnl. hydrogen bonding with residues of the Cif active site. From this effort, three compounds were identified that are 10-fold more potent toward Cif than our first-generation inhibitors and have no detectable thyroid hormone-like activity. These inhibitors will be useful tools to study the pathol. role of Cif and have the potential for clin. application.
