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.

One of the oldest and most widely used commercial enzyme inhibitors is aspirin, HPLC of Formula: C3H5NOS, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation. you can also check out more blogs about 2682-49-7

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.

Bioactive thiazole and benzothiazole derivatives

The heterocycles are the versatile compounds existing in almost all natural products and synthetic organic compounds, usually associated with one or the other biological activity. Among the heterocycles the thiazoles and benzothiazoles occupy a prominent position. They possess a broad range of biological activities and are foundin many potent biologically active molecules and drugs such as vitamin thiamine, sulfathiazol (antimicrobial drug), ritonavir (antiretroviral drug), abafungin (antifungal drug) and tiazofurin (antineoplastic drug). The thiazole moiety is abundantly found in natural products while benzothiazole moiety is rare. In this review we disclose the literature reports of thiazoles and benzothiazoles possessing different biological activities.

Asymmetric Acylation of sec-Alcohols with Twisted Amides Possessing Axial Chirality Induced by the Adjacent Asymmetric Center

This paper reports that axially chiral twisted amides serve as asymmetric acylating agents for sec-alcohols under neutral conditions. Kinetic resolution of various racemic sec-alcohols and desymmetrization of 1,2-, 1,3-, and 1,4-meso-diols were performed by using the twisted amides. The utility of this desymmetrization method was shown by the preparation of the synthetic intermediate 28 for macrolide antibiotic nodusmicin and 18-deoxynargenicin. The stereoselectivity of the acylation reactions is significantly dependent on the bulkiness of both the acyl group and the C-4 substituent of the chiral auxiliary. When an amide possessing an imidazolyl group at C-4 was employed, the stereoselectivity was reversed to give R esters. A possible working model of the acylation reaction is also described on the basis of the structural studies of the twisted amides by IR and 1H and 13C NMR spectroscopies and AMI calculations. These studies suggested that rotamer II is thermodynamically more stable than the others. The rotamer II has an axial chirality about its C(O)-N linkage that is induced by the adjacent chiral center. This would enable discrimination of the two enantiomeric hydroxy groups of the racemic alcohols or meso-diols.

Total Enantioselective Synthesis of the Endophytic Fungal Polyketide Phomolide H and Its Structural Revision

A total synthesis of the proposed structure of the natural polyketide-macrolactone phomolide H 2 has been achieved following a bidirectional strategy from l-tartaric acid. The originally assigned structure of phomolide H displayed discordant NMR spectroscopic data in comparison with synthetic 2. The synthetic strategy was extended to prepare diastereomers and epimeric methyl-ethers of the natural product, structural analysis of which revealed a match of the natural product with diastereomer 27. The structural revision of phomolide H from 2 to the methanol solvate of compound 27 is presented.

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.COA of Formula: C6H11NS2, you can also check out more blogs about76186-04-4
