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.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 2682-49-7, and how the biochemistry of the body works.Synthetic Route of 2682-49-7

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.

5-(1H-Indol-3-ylmethylene)-4-oxo-2-thioxothiazolidin-3-yl)alkancarboxylic Acids as Antimicrobial Agents: Synthesis, biological evaluation, and molecular docking studies

Background: Infectious diseases symbolize a global consequential strain on public health security and impact on the socio-economic stability all over the world. The increasing resistance to the current antimicrobial treatment has resulted in crucial need for the discovery and development of novel entity for the infectious treatment with different modes of action that could target both sensitive and resistant strains. Methods: Compounds were synthesized using classical methods of organic synthesis. Results: All 20 synthesized compounds showed antibacterial activity against eight Gram-positive and Gram-negative bacterial species. It should be mentioned that all compounds exhibited better antibacterial potency than ampicillin against all bacteria tested. Furthermore, 18 compounds appeared to be more potent than streptomycin against Staphylococcus aureus, Enterobacter cloacae, Pseudomonas aeruginosa, Listeria monocytogenes, and Escherichia coli. Three the most active compounds 4h, 5b, and 5g appeared to be more potent against MRSA than ampicillin, while streptomycin did not show any bactericidal activity. All three compounds displayed better activity also against resistant strains P. aeruginosa and E. coli than ampicillin. Furthermore, all compounds were able to inhibit biofilm formation 2- to 4-times more than both reference drugs. Compounds were evaluated also for their antifungal activity against eight species. The evaluation revealed that all compounds exhibited antifungal activity better than the reference drugs bifonazole and ketoconazole. Molecular docking studies on antibacterial and antifungal targets were performed in order to elucidate the mechanism of antibacterial activity of synthesized compounds. Conclusion: All tested compounds showed good antibacterial and antifungal activity better than that of reference drugs and three the most active compounds could consider as lead compounds for the development of new more potent agents.

Syntheses, characterization and evaluation of some 3-(Benzothiazol-2-yl)-2-(4-substituted phenyl) thiazolidin-4-ones as antimicrobial agents

Background: The increasing predominance of microbial resistance towards available antimicrobial drugs urges the need to develop novel antimicrobial agents that will be effective against resistant bacteria and fungi. Objective: A series of 3-(benzothiazol-2-yl)-2-(4-substituted phenyl) thiazolidin-4-one derivatives were synthesized as pharmacophore hybrid of benzothiazole and thiazolidin-4-one moieties as exclusive antimicrobial agents. Methods: Proposed compounds were synthesized by four step reactions. First three steps involved synthesis of phenylthiourea, benzothiazol-2-ylamine and Schiff?s base srespectively. Finally, Schiff`s baseswere cyclized in the presence of thioglycolic acid to yield 4-thiazolidinone derivatives (2a-g), characterized by spectroscopic and elemental analysis. Resulted compounds were evaluated for their in vitro antimicrobial activities against four bacterial (Staphylococcus aureus, Bacillus subtilis, Escherichia coli and Pseudomonas aeruginosa) and two fungal (A. niger and P. crysogenum) strains using agar diffusion method. The minimum inhibitory concentrations (MIC) of the synthesized compounds were also determined by tube dilution method. Results: All the compounds displayed good to moderate antimicrobial activity. Compound 2d was found most potent against Bacillus subtilis (MIC25mug/ml), whereas compound 2e was most active (MIC 25mug/ml) against Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa. Conclusion: The compounds having electron-withdrawing groups in the phenyl ring exhibited promising activity. A correlation between the antimicrobial activity and Log P was also established. Most active compounds can be considered as the potential antibacterial agents and deserve further investigation for their pharmacological and toxicological profiling.

A study of the antimicrobial activity of selected synthetic and naturally occurring quinolines

The antimicrobial activities of 60 naturally occurring and synthetic quinolines were studied. The quinolines were organised into seven structural subgroups and, using an in-house microtitre assay, were tested against a range of Gram-positive and Gram-negative bacteria, including a hospital isolate of meticillin-resistant Staphylococcus aureus (MRSA). The quinolines exhibiting good bioactivity [i.e. low minimum inhibitory concentration (MIC)] against two S. aureus strains were then assessed for their antimicrobial activity against a range of eight clinically isolated MRSA strains. The study showed that 30 of the tested compounds displayed antimicrobial activity, mostly against Gram-positive bacteria. The effects of substituent groups on the bioactivity of these quinolines have also been discussed. The quinoline 4-hydroxy-3-iodo-quinol-2-one (11) exhibited significant antimicrobial activity, being active against the MRSA clinical isolates with MIC values comparable with the antibiotic vancomycin used in the treatment of MRSA infections. In particular, 4-hydroxy-3-iodo-quinol-2-one (11) showed MIC values of 0.097 mug/mL against an Irish hospital MRSA-1 strain and 0.049 mug/mL against a distinct MRSA strain as well as a non-typeable MRSA strain.
