Flexibility of small molecular CD4 mimics as HIV entry inhibitors

CD4 mimics such as YIR-821 and its derivatives are small molecules which inhibit the interaction between the Phe43 cavity of HIV-1 gp120 with host CD4, an interaction that is involved in the entry of HIV to cells. Known CD4 mimics generally possess three structural features, an aromatic ring, an oxalamide linker and a piperidine moiety. We have shown previously that introduction of a cyclohexyl group and a guanidine group into the piperidine moiety and a fluorine atom at the meta-position of the aromatic ring leads to a significant increase in the anti-HIV activity. In the current study, the effects of conformational flexibility were investigated by introduction of an indole-type group in the junction between the oxalamide linker and the aromatic moiety or by replacement of the oxalamide linker with a glycine linker. This led to the development of compounds with high anti-HIV activity, showing the importance of the junction region for the expression of high anti-HIV activity. The present data are expected to be useful in the future design of novel CD4 mimic molecules.

Synthesis of Multifunctional Spirocyclic Azetidines and Their Application in Drug Discovery

The synthesis of multifunctional spirocycles was achieved from common cyclic carboxylic acids (cyclobutane carboxylate, cyclopentane carboxylate, l-proline, etc.). The whole sequence included only two chemical stepssynthesis of azetidinones, and reduction into azetidines. The obtained spirocyclic amino acids were incorporated into a structure of the known anesthetic drug Bupivacaine. The obtained analogues were more active and less toxic than the original drug. We believe that this discovery will lead to a wide use of spirocyclic building blocks in drug discovery in the near future.

Directing Quinone Methide-Dependent Alkylation and Cross-Linking of Nucleic Acids with Quaternary Amines

Polyamine and polyammonium ion conjugates are often used to direct reagents to nucleic acids based on their strong electrostatic attraction to the phosphoribose backbone. Such nonspecific interactions do not typically alter the specificity of the attached reagent, but polyammonium ions dramatically redirected the specificity of a series of quinone methide precursors. Replacement of a relatively nonspecific intercalator based on acridine with a series of polyammonium ions resulted in a surprising change of DNA products. Piperidine stable adducts were generated in duplex DNA that lacked the ability to support a dynamic cross-linking observed previously with acridine conjugates. Minor reaction at guanine N7, the site of reversible reaction, was retained by a monofunctional quinone methide-polyammonium ion conjugate, but a bisfunctional analogue designed for tandem quinone methide formation modified guanine N7 in only single-stranded DNA. The resulting intrastrand cross-links were sufficiently dynamic to rearrange to interstrand cross-links. However, no further transfer of adducts was observed in duplex DNA. An alternative design that spatially and temporally decoupled the two quinone methide equivalents neither restored the dynamic reaction nor cross-linked DNA efficiently. While di- and triammonium ion conjugates successfully enhanced the yields of cross-linking by a bisquinone methide relative to a monoammonium equivalent, alternative ligands will be necessary to facilitate the migration of cross-linking and its potential application to disrupt DNA repair.

Amine N-Oxide Kinetic Hydrate Inhibitor Polymers for High-Salinity Applications

A series of glycidyl amine N-oxide polyethers with cyclic and acyclic amine N-oxide side groups and their block copolymers with poly(propylene) oxide (M-n in the range of 1.8-6.4 kg/mol) have been synthesized and investigated as kinetic hydrate inhibitors (KHIs) using a structure II hydrate-forming gas mixture. Polymers based on cyclic amine N-oxides, containing poly(piperidine glycidyl amine N-oxide) units gave a remarkable KHI performance. The best polymers gave similar KHI performance to commercial poly(N-vinylcaprolactam) (PVCap) at the same concentration of 2500 ppm. In addition, upon heating to 95 degrees C, the best polymers had no cloud point at 2500 ppm (0.25 wt %), even in 15 wt % sodium chloride solution. Thus, these polymers possess excellent potential for injection into high-salinity- and high-temperature-produced fluids.

New 1,2,3-triazole based bis- and trisphosphine ligands: synthesis, transition metal chemistry and catalytic studies

The syntheses and transition metal chemistry of triazole-based bis- and tris-phosphines, 5-(diphenylphosphanyl)-1-(2-(diphenylphosphanyl)phenyl)-4-phenyl-1H-1,2,3-triazole (2), 5-(diphenylphosphanyl)-4(2-(diphenylphosphanyl)phenyl)-1-phenyl-1H-1,2,3-triazole (5), 1,4-bis(2-(diphenylphosphanyl)phenyl)1H-1,2,3-triazole (6) and 5-(diphenylphosphanyl)-1,4-bis(2-(diphenylphosphanyl)phenyl)-1H-1,2,3-triazole (7), are described. Bisphosphines 5 and 6 show versatile coordination behavior due to the presence of at least four donor atoms. The reactions of 5 and 6 with group VI metal carbonyl derivatives were found to be highly sensitive to the reaction conditions. Bisphosphine 5 upon treatment with [M (CO)4( piperidine)2] (M = Mo and W) yielded both P,P and P,N coordinated complexes [M(CO)4(5)] [M = Mo-kappa(2)-P,N (8); W-kappa(2)-P,N (9); Mo-kappa(2)- P,P (10); W-kappa(2)-P,P (11)], whereas 6 afforded only P,N coordinated complexes [{o-Ph2P(C6H4){1,2,3-N3C(o-Ph2P(C6H4))CH}-kappa(2)-P,N}Mo(CO)(4)] (12) and [{o-Ph2P(C6H4){1,2,3N(3)C(o-Ph2P(C6H4))CH}-kappa(2)-P,N}W(CO)(4)] (13). The reactions of 5 with [M(COD)Cl-2] (M = Pd and Pt) yielded kappa(2)-P,P chelate complexes 14 and 15, respectively, whereas the treatment of 6 with [Pd(COD)Cl-2] at ambient temperature resulted in the formation of a rare fused six-membered PCP pincer complex [{o-Ph2P(C6H4){1,2,3-N3C(o-Ph2P(C6H4))C}-kappa(3)-P, C,P}PdCl] (16). Similar reactions of 6 with [NiCl2(DME)] and [Pt(COD)Cl-2] in the presence of LiHMDS yielded [{o-Ph2P(C6H4){1,2,3-N3C(o-Ph2P(C6H4))C}-kappa(3)-P,C,P} NiCl] (17) and [{o-Ph2P(C6H4){1,2,3-N3C(o-Ph2P(C6H(4)))C}-kappa(3)-P,C,P}PtCl] (18), respectively. The reaction between 6 and [M(COD)Cl](2) (M = Rh and Ir) produced cationic complexes [{o-Ph2P(C6H4){1,2,3-N3C(o-Ph2P(C6H4))CH}-kappa(2)-P,N}Rh(C8H12)]Cl (19) and [{o-Ph2P(C6H4){1,2,3-N3C(o-Ph2P(C6H4))CH}-kappa(2)-P,N}Ir (C8H12)]Cl (20), respectively, whereas the reaction with [Rh(acac)(CO)(2)] resulted in a pincer complex [{o-Ph2P(C6H4){1,2,3-N3C(o-Ph2P(C6H4))C}-kappa(3)-P, C,P}Rh(CO)] (21). The structures of most of the compounds have been determined by single crystal X-ray analyses. The fused six-membered PCP palladium pincer complex 16 is found to be an excellent catalyst for the Mizoroki-Heck coupling reaction.

Theoretical Study of the Borono-Mannich Reaction with Pinacol Allenylboronate

A density functional theory study of the mechanism of the Borono-Mannich reaction using benzylamine and piperidine as representative examples of primary and secondary amines with pinacol allenylboronate is presented. The study shows that both reactions progress through coordination between the boron and the phenolic oxygen. Ring size strain and hydrogen bond activation appear to determine the observed divergent regioselectivity. In the case of benzylamine, the eight-membered ring transition structure that leads to the propargylamine exhibits a hydrogen bond between the hydrogen attached to the nitrogen and the phenolic oxygen (gamma-attack), whereas for piperidine a hydrogen bond between the hydrogen on the imine carbon and one of the oxygens of the pinacol group was observed in the six-membered ring transition structure toward the allenylamine (alpha-attack).

Synthesis, evaluation, and molecular properties prediction of substituted cinnamoylpiperazine derivatives as potential antinociceptive and anticonvulsive agents

A series of novel cinnamoylpiperazine derivatives (5a-5l) were synthesized as potential antinociceptive, and anticonvulsive agents. Various heterocyclic systems like piperidine, morpholine, piperazine, and N-arylpiperazine were combined with cinnamoyl or methylenedioxy cinnamoyl moieties to obtain a series of constrained analogs of cinnamides. Of these, compound 5e possessing 4-fluorophenyl substitution on the piperazine ring exhibited good antinociceptive activity in capsaicin and formalin-induced nociception methods, and also significant anticonvulsant activity in pentylenetetrazole and maximal electroshock-induced seizure methods. Further, all the derivatives were studied for molecular and preadmet properties. The activities of compound 5e were supported by molecular and preadmet properties for its in silico oral bioavailability and drug-likeness.

Molecular insights into the hydrodenitrogenation mechanism of pyridine over Pt/gamma-Al2O3 catalysts

The hydrodenitrogenation of nitrogen-containing heterocycles over noble metals has fundamental importance for energy and environmental science. To develop more efficient catalyst, mechanistic investigation has been conducted with a method combining in situ Fourier transformation infrared experiments and density functional theory calculations in this work. The in situ experiments indicate flatly adsorbed pyridine molecules convert to pyridinium and alpha-pyridyl species at higher temperature on metallic Pt of Pt/gamma-Al2O3 catalysts. Pyridine hydrogenation distinctly takes place at 150 degrees C with the appearance of methylene stretching vibrations, and a stepwise mechanism is identified as the temperature further increases. The adsorption, hydrogenation and hydrogenolysis of pyridine on Pt are studied in detail by theoretical calculations. In line with these findings, the geometry optimization confirms pyridine preferentially adsorbs on Pt(111) and Pt(211) both in a parallel configuration. Based on the Langmuir-Hinshelwood mechanism, the results show successive hydrogenation markedly lowers the energy barrier for subsequent hydrogenolysis. The C-N bond cleavage occurs via nucleophilic attack of pentahydropyridine, rather than piperidine, which determines the reaction products, including piperidine, n-pentylamine and n-pentane. The comparative study reveals both hydrogenation and hydrogenolysis are kinetically and thermodynamically more competitive on Pt(211) than Pt(111). Especially for hydrogenolysis, the coordinatively unsaturated Pt step atoms play an essential role in C-N bond cleavage. Thus, hydrogenolysis is more geometric-dependent than hydrogenation. This provides instructive information for the design of catalysts with adjustable product selectivity.
