Near-infrared luminescent PMMA-supported metallopolymers based on Zn-Nd schiff-base complexes

On the basis of self-assembly from the divinylphenyl-modified Salen-type Schiff-base ligands H2L1 (N,N?-bis(5-(3?- vinylphenyl)-3-methoxy-salicylidene)ethylene-1,2-diamine) or H2L 2 (N,N?-bis(5-(3?-vinylphenyl)-3-methoxy-salicylidene) phenylene-1,2-diamine) with Zn(OAc)2¡¤2H2O and Ln(NO3)3¡¤6H2O in the presence of pyridine (Py), two series of heterobinuclear Zn-Ln complexes [Zn(L n)(Py)Ln(NO3)3] (n = 1, Ln = La, 1; Ln = Nd, 2; or Ln = Gd, 3 and n = 2, Ln = La, 4; Ln = Nd, 5; or Ln = Gd, 6) are obtained, respectively. Further, through the physical doping and the controlled copolymerization with methyl methacrylate (MMA), two kinds of PMMA-supported hybrid materials, doped PMMA/[Zn(Ln)(Py)Ln(NO3) 3] and Wolf Type II Zn2+-Ln3+-containing metallopolymers Poly(MMA-co-[Zn(Ln)(Py)Ln(NO3) 3]), are obtained, respectively. The result of their solid photophysical properties shows the strong and characteristic near-infrared (NIR) luminescent Nd3+-centered emissions for both PMMA/[Zn(L n)(Py)Nd(NO3)3] and Poly(MMA-co-[Zn(L n)(Py)Nd(NO3)3]), where ethylene-linked hybrid materials endow relatively higher intrinsic quantum yields due to the sensitization from both 1LC and 3LC of the chromorphore than those from only 1LC in phenylene-linked hybrid materials, and the concentration self-quenching of Nd3+-based NIR luminescence could be effectively prevented for the copolymerized hybrid materials in comparison with the doped hybrid materials.

Synthesis and evaluation of nevirapine analogs to study the metabolic activation of nevirapine

Nevirapine (NVP) is widely used as a non-nucleoside reverse transcriptase inhibitor of HIV-1, however, it is associated with severe skin and liver injury. The mechanisms of these adverse reactions are not yet clear, but the metabolic activation of NVP is thought to be related to the injury process. Until now, several metabolic activation pathways of NVP have been reported. In this study, in order to identify the reactive metabolite of NVP mainly responsible for CYP inhibition and liver injury, we synthesized five NVP analogs designed to avoid the proposed bioactivation pathway and evaluated their metabolic stabilities, CYP3A4 time-dependent inhibitory activities, and cytotoxicity. As a result, only a pyrimidine analog of NVP, which could avoid the formation of a reactive epoxide intermediate, did not inhibit CYP3A4. Outside of this compound, the other synthesized compounds, which could avoid the generation of a reactive quinone-methide intermediate, inhibited CYP3A4 equal to or stronger than NVP. The pyrimidine analog of NVP did not induce cytotoxicity in HepG2 and transchromosomic HepG2 cells, expressing major four CYP enzymes and CYP oxidoreductase. These results indicated that the epoxide intermediate of NVP might play an important role in NVP-induced liver injury.

Synthesis and biological screening of some novel 6-substituted 2-alkylpyridazin-3(2H)-ones as anti-inflammatory and analgesic agents

Some novel derivatives of 2-alkyl 6-substituted pyridazin-3(2H)-ones were synthesized by condensation of 3,6-dichloropyridazine with the sodium salt of benzyl cyanide, followed by hydrolysis and coupling with alkyl halides. The synthesized compounds were screened as cyclooxygenase (COX)-1/COX-2 inhibitors and as analgesic and anti-inflammatory agents. Among the synthesized compounds, 6-benzyl-2-methylpyridazin-3(2H)-one (4a), 6-benzoyl-2-propylpyridazin-3(2H)-one (8b), and 6-(hydroxy(phenyl)methyl)-2-methylpyridazin-3(2H)-one (9a) displayed the highest COX-2 selectivity indices of 96, 99, and 98, respectively, and analgesic efficacies of 47%, 46%, and 45% protection, respectively. Also, compounds 4a, 8b, and 9a showed anti-inflammatory activities of 65%, 60%, and 62% inhibition of edema, respectively, at a dose of 10 mg/kg, which is higher than that of diclofenac (58% inhibition of edema).

(-)-Mirabazole B (1), an alkaloid consisting of four successive thiazoline/thiazole rings, has been synthesized in a convergent route. The key intermediate, a linear tripeptide amide 13 composing of three S-benzyl-2-methylcysteine residues, was prepared using 2-chloro-1,3-dimelhyl-imidazolidium hexafluorophosphate (CIP) in the presence of 1-hydroxy-7-azabenzotriazole (HOAt) as a coupling agent. The successive thiazoline/thiazole rings were constructed by TiCl4-mediated cyclization followed by Hantzsch reaction without difficulty.

Discovery of a novel series of potent non-nucleoside inhibitors of hepatitis C virus NS5B

Hepatitis C virus (HCV) is a major global public health problem. While the current standard of care, a direct-acting antiviral (DAA) protease inhibitor taken in combination with pegylated interferon and ribavirin, represents a major advancement in recent years, an unmet medical need still exists for treatment modalities that improve upon both efficacy and tolerability. Toward those ends, much effort has continued to focus on the discovery of new DAAs, with the ultimate goal to provide interferon-free combinations. The RNA-dependent RNA polymerase enzyme NS5B represents one such DAA therapeutic target for inhibition that has attracted much interest over the past decade. Herein, we report the discovery and optimization of a novel series of inhibitors of HCV NS5B, through the use of structure-based design applied to a fragment-derived starting point. Issues of potency, pharmacokinetics, and early safety were addressed in order to provide a clinical candidate in fluoropyridone 19.

Replacement of glycine with dicarbonyl and related moieties in analogues of the C-terminal pentapeptide of cholecystokinin: CCK2 agonists displaying a novel binding mode

Recent advances in the field of cholecystokinin have indicated the possible occurrence of multiple affinity states of the CCK2 receptor. Besides, numerous pharmacological experiments performed ‘in vitro’ and ‘in vivo’ support the eventuality of different pharmacological profiles associated to CCK2 ligands. Indeed, some agonists are essentially anxiogenic and uneffective in memory tests, whereas others are not anxiogenic and appear as able to reinforce memory. The reference compound for the latter profile is the CCK-8 analogue BC 264 (Boc-Tyr(SO3H)-gNle-mGly-Trp-(NMe)Nle-Asp-Phe-NH2). However, although tetrapeptide ligands based on CCK-4 (Trp-Met-Asp-Phe-NH2) are known to possess sufficient structural features for CCK2 recognition, none shares the properties of BC 264. Hence we have developed new short peptidic or pseud-opeptidic derivatives containing the C-terminal tetrapeptide of BC 264. Our results indicate that some compounds characterized by the presence of two carbonyl groups at the N-terminus, as in 2b (HO2C-CH2-CONH-Trp-(NMe)Nle-Asp-Phe-NH2), are likely to show a BC 264-like profile, bind to the CCK2 receptor in a specific way, and display remarkable affinities (2b: 0.28 nM on guinea-pig cortex membrane preparations). This original binding mode is discussed and further enlightened by NMR and molecular modeling studies.
