Pharmacokinetics of 2-oxothiazolidine-4-carboxylate, a cysteine prodrug, and cysteine

The pharmacokinetics of both 2-oxothiazolidine-4-carboxylate (OTZ), a prodrug of cysteine, and total blood cysteine (cysteine plus cystine) were investigated in 18 healthy volunteers. OTZ was given either as a single, 2- hour intravenous infusion (56-66 mg/kg) or similarly infused (70-100 mg/kg) every 8 hours for four doses. Blood was assayed for OTZ, total blood cysteine, and glutathione. The pharmacokinetics of OTZ were analyzed alone and simultaneously with total cysteine using the NONMEM software package (University of California at San Francisco. The pharmacokinetics of OTZ were best described by Michaelis-Menten kinetics with parallel first-order elimination. OTZ was efficiently removed from the plasma. The Michaelis- Menten route of elimination was attributed to conversion of OTZ to total cysteine. At plasma OTZ concentrations equal to the Michaelis constant Km, 84% of OTZ was converted to total cysteine. These findings suggest that OTZ administered intravenously is an efficient means of increasing total blood cysteine.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 19771-63-2 is helpful to your research. Electric Literature of 19771-63-2

Synthesis and in vitro anti-breast cancer evaluation of some novel benzimidazole ?pyridine conjugates

A new series of benzimidazole bearing pyridine derivatives were synthesized by condensation of 1,2-phenylenediamine with 2-oxo-1,2-dihydro-pyridine-3-carboxylic acid derivative 2 in phosphoric acid to give 3-(1Hbenzo[ d]imidazol-2-yl)-pyridin-2(1H)-one derivative 3. Compound 3 on further reaction with a mixture of phosphorus oxychloride and phosphorus pentachloride gave 2-(2-chloro-) pyridin-3-yl)-1H-benzo[d] imidazole derivative 4. Moreover, 4 were reacted with different amines to give 3-(1H-benzo[d]imidazol-2-yl)-N-(substituted) pyridin-2-amine derivatives 5a-c. Meanwhile, N-(N-(substituted) sulfamoyl) pyridin-3-yl)-1H-benzo[d]imidazole-1-carboxamide derivatives 7a,b were synthesized by reaction of 5c with chlorosulfonyl isocyanate to give 2-(pyridin-3-yl)-1H-benzo [d]imidazole-1-carbonyl) sulfamoyl chloride derivative followed by reaction of the latter with different amines. On the other hand, upon treatment compound 4 with hydrazine hydrate gave the hydrazide derivative 8. The reaction of compound 8 with different alkyl/arylisothiocyanates gave the corresponding thiosemicarbazide derivatives 9a-d, while their cyclo condensation reaction with ethyl chloro acetate gave the corresponding thiazolidin-4-one derivatives 10a-c. Moreover, condensation of 10a,c with aromatic aldehydes afforded the corresponding 5-arylidine-thiazolidin-4-one derivatives 11a,b. Cytotoxic evaluation of some of the newly synthesized compounds against human breast carcinoma cell line MCF-7 revealed that, these compounds showed promising activity compared with Doxorubicin as positive control.

Discovery of a COX-2 selective inhibitor hit with anti-inflammatory activity and gastric ulcer protective effect

Aim: A novel series of 2-arylimino-5-arylidenethiazolidin-4-ones 12a-n were synthesized and all the target compounds were fully characterized by IR, 1H NMR, 13C NMR, mass spectroscopy and elemental analysis. Materials & methods: All the target compounds were evaluated for their COX inhibition by enzyme immunoassay kit and in vivo anti-inflammatory activity. Results: Tested compounds were found more potent inhibitors of COX-2 (IC50 = 0.54-3.14 M) than COX-1 (IC50 = 4.97-11.52 M). The ulcerogenic liability of compounds 12(d, e, f, h, k, m) was performed and showed gastric safety more than or comparable to celecoxib. Conclusion: In addition, docking study of the most potent and selective compound 12h into COX-2 active site revealed that this target compound assumed interactions and binding pattern similar to that of as a cocrystallized ligand bromocelecoxib (S-58).

Discovery, synthesis, and structure-activity relationship development of a series of N -4-(2,5-dioxopyrrolidin-1-yl)phenylpicolinamides (VU0400195, ML182): Characterization of a novel positive allosteric modulator of the metabotropic glutamate receptor 4 (mGlu4) with oral efficacy in an antiparkinsonian animal model

There is an increasing amount of literature data showing the positive effects on preclinical antiparkinsonian rodent models with selective positive allosteric modulators of metabotropic glutamate receptor 4 (mGlu4). However, most of the data generated utilize compounds that have not been optimized for druglike properties, and as a consequence, they exhibit poor pharmacokinetic properties and thus do not cross the blood-brain barrier. Herein, we report on a series of N-4-(2,5-dioxopyrrolidin-1-yl) phenylpicolinamides with improved PK properties with excellent potency and selectivity as well as improved brain exposure in rodents. Finally, ML182 was shown to be orally active in the haloperidol induced catalepsy model, a well-established antiparkinsonian model.

The design and optimization of a series of 2-(pyridin-2-yl)-1H-benzimidazole compounds as allosteric glucokinase activators

The optimization of a series of benzimidazole glucokinase activators is described. We identified a novel and potent achiral benzimidazole derivative as an allosteric GK activator. This activator was designed and synthesized via removal of the chiral center of the lead compound, 6-(N-acylpyrrolidin-2-yl)benzimidazole. The activator exhibited good PK profiles in rats and dogs, and significant hypoglycemic efficacy at 1 mg/kg po dosing in a rat OGTT model. The binding site and binding mode of the benzimidazole class of GKA with GK protein was confirmed by X-ray crystallographic analysis.

Enantioselective synthesis of structurally intricate and complementary polyoxygenated building blocks of spongistatin 1 (altohyrtin a)

Enantioselective approaches to the construction of four complex building blocks of the structurally intricate marine macrolide known as spongistatin 1 are presented. The first phase of the synthetic effort relies on a practical approach to a desymmetrized, enantiomerically pure spiroketal ring system incorporating rings A and B. Concurrently, the C17-C28 subunit, which houses one-fifth of the stereogenic centers of the target in the form of rings C and D, was assembled via a composite of stereocontrolled aldol condensations. Once arrival at the entire C1-C28 sector had been realized, routes were devised to provide two additional highly functionalized sectors consisting of C29-C44 and C38-C51. A series of subsequent transformations including cyclization of the E ring and hydroboration to afford the B-alkyl intermediate for the key Suzuki coupling to append the side chain took advantage of efficient stereocontrol. Ultimately, complete assembly and functionalization of the western EF sector of spongistatin was thwarted by an inoperative Suzuki coupling step intended to join the side chain to the C29-C44 sector, and later because of complications due to protecting groups, which precluded the complete elaboration of the late stage C29-C51 intermediate.

Recent developments of coumarin hybrids as anti-fungal agents

Fungi place a huge burden on global healthcare systems attributed to the fact that fungal infections are responsible for the high morbidity and mortality rates in patients who received stem cell transplantation, antineoplastic chemotherapy, organ transplants or suffered Human Immunodeficiency Virus (HIV) infection. Unfortunately, almost none of the representative anti-fungal agents currently used in clinical therapy are ideal in terms of efficacy, anti-fungal spectrum or safety. Moreover, the rapid development of resistance to existing anti-fungal drugs has further aggravated the mortality and spread of fungi, creating an urgent need for novel anti-fungal agents. The broad spectrum of biological activities and successful usage in clinic made coumarins a promising anti-fungal candidate. Furthermore, hybridization of other pharmacophores with coumarin motif may enhance the anti-fungal efficacy, broaden the anti-fungal spectrum and improve the safety profiles. Thus, numerous coumarin hybrids have been assessed for their anti-fungal activities, and some of them showed promising potency and may have a novel mechanism of action. This review aims to outline the recent development of coumarin hybrids as potential anti-fungal agents and summarize their Structure-Activity Relationship (SAR) to provide an insight for rational designs of more active agents.
