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.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Synthetic Route of 19771-63-2, you can also check out more blogs about19771-63-2

A retrospect study on thiazole derivatives as the potential antidiabetic agents in drug discovery and developments

Background: Heterocycles containing thiazole, a moiety with sulfur and nitrogen is a core structure which is found in a number of biologically active compounds. The thiazole ring is notable as a component of the certain natural products,such as vitamin B1 (thiamine) and penicillins. Thiazole is also known as wonder nucleus and has uses in different biological fields. A number of new compounds contain heterocycle thiazole moieties, thus it is one of the important areas of research. Methods: We searched the scientific database using relevant keywords. Among the searched literature only peer-reviewed papers were collected which addresses our questions. The retrieved quality research articles were screened and analyzed critically. The key findings of these studies were included along with their importance.Results: The quality research articles included in this review were selected for the lifethreatening diseases i.e. diabetes, which is one of the serious issues all over the globe with an estimated worldwide prevalence in 2016 of 422 million people, which is expected to rise double to by 2030. Since 1995, there has been an explosion of the introduction of new classes of pharmacological agents having thiazole moieties. However, most of the drugs can cause noncompliance, hypoglycemia, and obesity. Thus, new antidiabetic drugs with thiazole moieties came up with improved compliance and reduced side effects such as pioglitazone (Actos), rosiglitazone (Avandia), netoglitazone,DRF-2189, PHT46, PMT13, DRF-2519. With such a great importance, research in thiazole is part of many academic and industrial laboratories worldwide.Conclusion: The present review describes the importance of thiazole nucleus and its derivatives as antidiabetic agents with an emphasis on the past as well as recent developments.

Total synthesis of the lipid mediator PD1n-3 DPA: Configurational assignments and anti-inflammatory and pro-resolving actions

The polyunsaturated lipid mediator PD1n-3 DPA (5) was recently isolated from self-resolving inflammatory exudates of 5 and human macrophages. Herein, the first total synthesis of PD1n-3 DPA (5) is reported in 10 steps and 9% overall yield. These efforts, together with NMR data of its methyl ester 6, confirmed the structure of 5 to be (7Z,10R,11E,13E,15Z,17S,19Z)-10,17- dihydroxydocosa-7,11,13,15,19-pentaenoic acid. The proposed biosynthetic pathway, with the involvement of an epoxide intermediate, was supported by results from trapping experiments. In addition, LC-MS/MS data of the free acid 5, obtained from hydrolysis of the synthetic methyl ester 6, matched data for the endogenously produced biological material. The natural product PD1 n-3 DPA (5) demonstrated potent anti-inflammatory properties together with pro-resolving actions stimulating human macrophage phagocytosis and efferocytosis. These results contribute new knowledge on the n-3 DPA structure-function of the growing numbers of specialized pro-resolving lipid mediators and pathways.

Spectroscopic investigations of the interactions of potential antitumor amino-thiazolidinone platinum (II) compounds with human serum albumin

An amino-thiazolidinone platinum(II) compound which could rapidly induce apoptosis in tumor cells and showed no cross resistance against the cisplatin-resistant cells, was firstly to study of protein-drug interactions. To investigate the potential of Pt(II) compounds as therapeutic drugs, two Pt(II) complexes (1 and 2) were explored the influences based on their interaction in vitro with human serum albumin (HSA) by fluorescence spectrometry and UV?Vis absorption. The binding interactions of two compounds with HSA results in the formation of corresponding HSA-drug complexes, van der Waals forces and hydrogen bonding played key roles in stabilizing these complexes. Both of two compounds were through a dynamic quenching mechanism, this dynamic reversible binding process was of great significance to the equilibrium of drug concentrations in vivo, which ensured that the internal environment of the organism was in a relatively stable state.

Quinolidene-rhodanine conjugates: Facile synthesis and biological evaluation

A series of rhodanine incorporated quinoline derivatives were efficiently synthesized using reusable DBU acetate as ionic liquid and evaluated for their in?vitro antitubercular activity against Mycobacterium tuberculosis H37Ra (MTB) (ATCC 25177) and Mycobacterium bovis BCG (ATCC 35743) both in active and dormant state. Compounds 3e, 3f, 3g, 3h and 3i exhibited very good antitubercular activity. The active compounds were studied for cytotoxicity against HUVEC, THP-1, macrophages, A549, PANC-1 and HeLa cell lines using modified MTT assay and were found to be noncytotoxic. Inactivity of all these compounds against Gram positive and Gram negative bacteria indicates their specificity towards the MTB. Further, the synthesized compounds have been screened for their in?vitro antifungal activity. In addition, the molecular docking studies revealed the binding modes of these compounds in active site of Zmp1 enzyme, which in turn helped to establish a structural basis of inhibition of mycobacteria. The results of present study clearly indicate the identification of some novel, selective and specific inhibitors against MTB that can be explored further for potential antitubercular drug.

Synthesis of polycyclic benzofused nitrogen heterocycles via a tandem ynamide benzannulation/ring-closing metathesis strategy. Application in a formal total synthesis of (?)-FR900482

A two-stage “tandem strategy” for the synthesis of benzofused nitrogen heterocycles is described that is particularly useful for the construction of systems with a high level of substitution on the benzenoid ring. The first stage in the strategy involves a benzannulation based on the reaction of cyclobutenones with ynamides. This cascade process proceeds via a sequence of four pericyclic reactions and furnishes a multiply substituted aniline derivative which can bear a variety of functionalized substituents at the position ortho to the nitrogen. In the second stage of the tandem strategy, ringclosing metathesis generates the nitrogen heterocyclic ring. This two-step sequence provides efficient access to highly substituted dihydroquinolines, benzazepines, benzazocines, and related benzofused nitrogen heterocyclic systems. The application of this chemistry in a concise formal total synthesis of the anticancer agents (?)-FR900482 and (?)-FR66979 is described. 2011 American Chemical Society.

Studies of the reactions between indole-2,3-diones (isatins) and 2-aminobenzylamine

Reflux of equimolecular amounts 2-aminobenzylamine and isatins in acetic acid produced indolo[3,2-c]quinolin-6-ones in good yields. A proposed mechanism involving initial formation of a spiro compound is given. This isolable intermediate subsequently rearranges via a sequential isocyanate ring opening and a cyclisation process to a urea derivative which finally cyclized to the indolo[3,2-c]quinolin-6-ones. The urea derivative could be prepared separately and cyclized selectively to indolo[3,2-c]quinolin-6-one. Reaction of N-acetylisatin with 2-aminobenzylamine at room temperature yielded the 1,4-benzodiazepinone 3-(2-acetamidophenyl)-1,5-dihydro-1,4-benzodiazepin-2-one whereas its isomer 2(2-acetamidophenyl)-4,5-dihydro-1,4-benzodiazepin-3-one was obtained from 2-(2-acetylaminophenyl)-N-(2-aminobenzyl)-2-oxoacetamide in acetic acid at room temperature. The previously unknown linear isomer of indolo[3,2-c]quinolin-6-one, i.e. indolo[2,3-b]quinolin-11-one, has been prepared by thermal (260C) cyclization of methyl 2-phenylamino indole-3-carboxylate, which in turn was prepared in two steps from methyl indole-3-carboxylate.
