Isothiocyanatoluminol as a chemiluminescence labeling reagent for amino acids and proteins

Isothiocyanatoluminol (ITL) was successfully synthesized from the reaction between luminol and thiophosgene in the presence of triethylamine. The optimized conditions were extended for the preparation of isothiocyanatoisoluminol (ITIL) and phenyl isothiocyanate (PI). The chemiluminescence (CL) of ITL was comparable to luminol. ITL was used as a CL labeling reagent for amino acid and bovine serum albumin (BSA) in which the -NH2 terminus of amino acid residue present in BSA acts as the labeling site.

Inhibition of aldose reductase and sorbitol accumulation by hydroalcoholic extract of propolis

Background: Increased polyol pathway activity and subsequent occurrences, and particular sorbitol accumulation are noticed in the development of various secondary complications of diabetes. Aldose reductase (ALR2) or aldo-ketoreductase (AKR1B1) as the first and rate limiting enzyme of this pathway is a good target for new drugs for diabetes complications. A good inhibitor should inhibit aldehyde reductase (ALR1), the other member of this family lesser than ALR2. Bee propolis is a known substance in ancient medicine, but its effect on polyol pathway is unknown. Objectives: The current study aimed to investigate the effect of hydroalcoholic extract of propolis (HAEP) on partial purified bovine lens ALR2, also the effect of HAEP on sorbitol accumulation in human erythrocytes in high-glucose condition (ex vivo). Materials and Methods: Total protein was determined by lowery method. Bovine lens ALR2 was partially purified by gel filtration chromatography on sephadexTM G25. Bovine cortex kidney ALR1 was partially purified by diethylaminoethyl (DEAE) precipitation. The hydroalcoholic extract was obtained from frozen propolis. The enzyme activity and sorbitol accumulation in erythrocytes were determined spectroflourimetrically. Results: It was found that ethyl acetate (EthAc) fraction (the more potent fraction) of HAEP inhibited ALR2 by IC50 value of 1.12 mg/mL up to 50% and this fraction can inhibit ALR2 8.25-fold greater than ALR1. In addition, it was found that this fraction could decrease sorbitol accumulation in human erythrocytes under high-glucose condition. Conclusions: The obtained results indicated that propolis may be a good candidate for more studies to find new drugs for the treatment of secondary complications of diabetes.

Chemiluminescent detection of enzymatically produced H2S

Hydrogen sulfide (H2S) has emerged as an important biological signaling molecule. To better understand the multifaceted biological roles of H2S, the development of selective and sensitive biocompatible assays for H2S is becoming increasingly important. Motivated by these challenges, our laboratory is developing new methods to further detect and monitor biological H2S. Here, we describe in detail our recent advances in the development and the use of chemiluminescence-based H2S sensors to assist other investigators with use of these chemical tools. We highlight the use of these tools use by displaying their selectivity and high sensitivity toward H2S and provide examples of assays we have developed to detect enzymatically produced H2S.

Automated assays for von Willebrand factor activity

von Willebrand factor (VWF) ristocetin cofactor activity (VWF:RCo) by platelet aggregometry has been considered the gold standard for evaluating the ability of VWF to bind platelets for over 40 years. Many automated systems no longer require platelets and rather rely on agglutination of latex particles. Automated methods of measuring VWF activity have improved performance characteristics and are performed on the same coagulation instruments used for routine testing via immunoturbidimetric methodology. Alternatively, a newer chemiluminescence assay system for measuring VWF activity demonstrates excellent performance characteristics. As these methods are becoming widely used, it is important to assess their performance in diagnosing and monitoring different types of von Willebrand disease. We review the automated methodologies and the published performance of these VWF assays. Advantages and limitations of these automated methods are discussed.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Design, synthesis, characterization, QSAR, docking, anti-inflammatory and analgesic evaluation of some new phthalazinediones

Background: phthalazine derivatives were reported to possess anticonvulsant, cardiotonic, antibacterial, analgesic, anti-inflammatory, and anti-microbial activity. In the current study, we applied the QSAR for prediction of newly phthalazinediones incorporating thioamide moiety aiming to reach a more potent anti-inflammatory and Analgesic agent. Methods: Phthalazinediones 10-15 have been synthesized through condensation of dibenzobarallene 3 with thiosemicarbazides 4-8. One equation was predicted using quantitative structure activity relationship (QSAR) and regression analysis for the anti-inflammatory activity with a regression correlation (R) close to unity. The docking studies were performed to investigate the biological trends of the organic compounds (thiol form) against cyclooxygenas- 2 enzyme, which is a responsible inflammation mediator by using Molgro Virtual Docker (MVD) software. The anti-inflammatory activity and analgesic effect of the thioamides 10-15 were determined by collagen II-adjuvant induced paw edema test in rats. Results: Compounds 10, 11, 12, and 14, exhibited promising anti-inflammatory activity. Furthermore, in the pain scoring, compounds 10, 11 and 12 were found to be more effective than piroxicam and the order of the analgesic effect of the investigated compounds is as followed 14 > 12 > 10 > 11 > 15. Conclusion: It is clear from the foregoing that the compound 14 is a promising compound if future pharmacological detailed studies. This is consistent with what has been predictable equation 1 in this study.

The importance of triazole scaffold in the development of anticonvulsant agents

Epilepsy is one of the most important neurological disorders with high prevalence worldwide. Many epileptic patients are not completely treated with available drugs and need multiple therapies. Also, many antiepileptic drugs have shown unwanted side effects and drug interactions. Therefore there are continuing interests to find new anticonvulsant drugs. Triazole ring has been found in the structure of many compounds with diverse biological effects. Due to the success of several triazole-containing drugs that entered the pharmaceutical market as CNS-active drugs, this class of heterocyclic compounds has great importance for discovery and development of new anticonvulsant drugs. In this article, we have tried to summarize the latest efforts which have been made in the design and development of triazole-derived anticonvulsant agents.

Visible-Light-Induced Copper-Catalyzed Decarboxylative Coupling of Redox-Active Esters with N-Heteroarenes

Herein we report a protocol for visible-light-induced copper-catalyzed decarboxylative coupling reactions between N-heteroarenes and redox-active esters. Various N-hydroxyphthalimide esters reacted with isoquinoline, quinoline, pyridine, pyrimidine, quinazoline, phthalazine, phenanthridine, and pyridazine to give the corresponding products in modest to excellent yields. The reactions proceed under mild conditions and have a broad scope and high functional group tolerance. Mechanistic studies revealed that the catalytic behavior of CuI photocatalyst generated in situ was consistent with that of preformed [Cu(dmp)(xantphos)]BF4.
