Protection against acetaminophen-induced hepatotoxicity by L-CySSME and its N-acetyl and ethyl ester derivatives

We have recently observed that S-(2-hydroxyethylmercapto)-L-cysteine (L-CySSME), the mixed disulfide of L-cysteine and 2-mercaptoethanol, prevented cataracts induced in mice by acetaminophen (ACP) by functioning as a prodrug of L-cysteine and protecting the liver. This prompted the evaluation of the more lipophilic N-acetyl (Ac-CySSME) and ethyl ester (Et-CySSME) derivatives of L-CySSME as proprodrug forms, as well as the “D” enantiomer, as hepatoprotective agents. Serum ALT levels were measured at 24 hours after a toxic but nonlethal dose of ACP that insured 48 hour survival of the animals. Since the increases in ALT produced were highly variable (even after log transformation) and complicated the statistical analyses, we calculated confidence intervals for the mean ALT levels for each treatment group. This enabled comparisons to be made of the efficacy of L-CySSME as well as Ac-CySSME and Et-CySSME with other representative prodrugs of L-cysteine, namely, 2(RS)-methylthiazolidine-4(R)-carboxylic acid (MTCA), L-2-oxothiazolidine-4-carboxylic acid (OTCA), and N-acetyl-L-cysteine (NAC), in protecting the liver. It was shown that L-CySSME and MTCA administered intraperitoneally at 2.5 mmol/kg were superior to the other cysteine prodrugs at equimolar doses in protecting mice from hepatotoxicity elicited by a 400 mg/kg (2.65 mmol/kg) dose of ACP given i.p. 30 minutes prior to the prodrugs. The “D” form of CySSME was totally without protective effect. Oral doses of the prodrugs even at 2x the i.p. dose were less effective, although MTCA was the most protective.

Novel heterocyclic hybrids based on 2-pyrazoline: Synthesis and assessment of anti-inflammatory and analgesic activities

Aim and Objective: A series of new 2-pyrazoline analogues were synthesized. The structures of the synthesized compounds were elucidated by the analytical and spectroscopic data. Some selected compounds were screened for the anti-inflammatory activity by using animal model of carrageenan-induced paw edema in mice. Additionally, the analgesic and acute toxicity of these compounds were evaluated and exhibited reasonable results. The anti-oxidant and anti-inflammatory effects of these compounds were established by measuring the contents of malondialdehyde (MDA), reduced glutathione (GSH), nitric oxide (NO), and tumor necrosis factor alpha (TNF-alpha) in the edema paw tissue. Materials and Methods: All chemicals and reagents used in current study were of analytical grade. Melting points were determined using APP. Digital ST 15 melting point apparatus and are uncorrected. FT-IR spectra were recorded on a Pye-Unicam SP3-100 spectrophotometer in KBr pellet. All 1H and 13C NMR spectra were recorded on AVANCE-III (400 MHz) High Performance FT-NMR Spectrometer Brucker (Switzerland) and some 1H NMR spectra were recorded on Varian EM-360L NMR Spectrophotometer (60 MHz) (USA) in CDCl3 or DMSO-d6 as solvent. Chemical shifts are reported in sigma units and the coupling constants (J) are reported in hertz. C, H, N and S analyses were performed with a Vario EL C, H, N, S Analyzer. Carrageenan (product number C1013) was obtained from Sigma-Aldrich (USA). Results: The structures of the compounds were confirmed by IR, 1H NMR, 13C NMR, and elemental analyses. The results of pharmacological activity revealed that compounds 5, 6, 7, and 15 could be recognized as potential multi-potent anti-inflammatory. Conclusion: A simple and suitable method for the synthesis of new pharmacophore was reported. We have designed nineteen heterocycles related to pyrazoline ring, and evaluated eleven of them for their antiinflammatory, analgesic and acute toxicity activities. Compounds 5, 6, 7, and 15 proved to be the interesting compounds, they have high anti-inflammatory activity. However, all the selected compounds show remarkable analgesic activity.

Benzothiazole derivatives as anticancer agents

Benzothiazole (BTA) belongs to the heterocyclic class of bicyclic compounds. BTA derivatives possesses broad spectrum biological activities such as anticancer, antioxidant, anti-inflammatory, anti-tumour, antiviral, antibacterial, anti-proliferative, anti-diabetic, anti-convulsant, analgesic, anti-tubercular, antimalarial, anti-leishmanial, anti-histaminic and anti-fungal among others. The BTA scaffolds showed a crucial role in the inhibition of the metalloenzyme carbonic anhydrase (CA). In this review an extensive literature survey over the last decade discloses the role of BTA derivatives mainly as anticancer agents. Such compounds are effective against various types of cancer cell lines through a multitude of mechanisms, some of which are poorly studied or understood. The inhibition of tumour associated CAs by BTA derivatives is on the other hand better investigated and such compounds may serve as anticancer leads for the development of agents effective against hypoxic tumours.
