Synthesis and biological evaluation of the new 1,3-dimethylxanthine derivatives with thiazolidine-4-one scaffold

Background: The xanthine structure has proved to be an important scaffold in the process of developing a wide variety of biologically active molecules such as bronchodilator, hypoglycemiant, anticancer and anti-inflammatory agents. It is known that hyperglycemia generates reactive oxygen species which are involved in the progression of diabetes mellitus and its complications. Therefore, the development of new compounds with antioxidant activity could be an important therapeutic strategy against this metabolic syndrome. Results: New thiazolidine-4-one derivatives with xanthine structure have been synthetized as potential antidiabetic drugs. The structure of the synthesized compounds was confirmed by using spectral methods (FT-IR, H-1-NMR, C-13-NMR, F-19-NMR, HRMS). Their antioxidant activity was evaluated using in vitro assays: DPPH and ABTS radical scavenging ability and phosphomolybdenum reducing antioxidant power assay. The developed compounds showed improved antioxidant effects in comparison to the parent compound, theophylline. In the case of both series, the intermediate (5a-k) and final compounds (6a-k), the aromatic substitution, especially in para position with halogens (fluoro, chloro), methyl and methoxy groups, was associated with an increase of the antioxidant effects. Conclusions: For several thiazolidine-4-one derivatives the antioxidant effect of was superior to that of their corresponding hydrazone derivatives. The most active compound was 6f which registered the highest radical scavenging activity.

DESIGN, SYNTHESIS AND IN-SILICO STUDY OF NOVEL SERIES OF 2-PHENYL-3-(5-SULFANYL-1,3,4-THIADIAZOL-2-YL)-1,3-THIAZOLIDIN-4-ONE DERIVATIVES WITH POTENTIAL ANTI-TUBERCULAR ACTIVITY

In an attempt to identify potential new agents active against tuberculosis with Shikimate kinase as the target, a novel series of 2-phenyl- 3-(5-sulfanyl-1,3,4-thiadiazol-2-yl)-1,3-thiazolidin-4-one derivatives were synthesized by convenient one-pot three-component reaction of amine, aldehyde and mercaptoacetic acid on montmorillonite KSF clay as a solid acidic catalyst in good yields. The structures of the newly synthesized compounds were confirmed by IR, H-1-NMR and elemental analysis and were subjected for anti-tubercular activity by Microplate Alamar Blue Assay (MABA) against Mycobacterium tuberculosis H37Rv. Docking and ADMET studies were used to better describe the titled compounds as potential anti-tubercular agents. The compound, 2-(3,4-dimethoxyphenyl)-3-(5-sulfanyl-1,3,4-thiadiazol-2-yl)-1,3-thiazolidin-4-one(4j), was found to be the most active against Mycobacterium tuberculosis H37Rv with MIC of 1.6 mu g/ml and good drug likeness and dock scores. Molecular docking study revealed that the molecules fit well into the cavity of Shikimate kinase. Also, the molecular properties and bioactivity scores for the synthesized compounds obtained by in-silico studies were found to be within the acceptable range defined for human use revealing their potential as possible drug-like compounds. The anti-tubercular activity of the titled compounds was comparable to that of the standard drug Isoniazid and Ciprofloxacin. The results indicate that the synthesized thiadiazolyl-thiazolidinone derivatives may have an affinity towards Shikimate kinase active site which can be further explored for selective target based studies. Thus these compounds could act as a potential lead for further anti-tubercular studies.

Novel Thiazolidin-4-ones as Potential Non-Nucleoside Inhibitors of HIV-1 Reverse Transcriptase

Background: HIV is the causative agent of Acquired Immunodeficiency Syndrome (AIDS), an infectious disease with increasing incidence worldwide. Non-nucleoside reverse transcriptase inhibitors (NNRTIs) play an important role in the treatment of AIDS. Although, many compounds are already being used as anti-HIV drugs, research for the development of new inhibitors continues as the virus develops resistant strains. Methods: The best features of available NNRTIs were taken into account for the design of novel inhibitors. PASS (Prediction of activity spectra for substances) prediction program and molecular docking studies for the selection of designed compounds were used for the synthesis. Compounds were synthesized using conventional and microwave irradiation methods and HIV RT inhibitory action was evaluated by colorimetric photometric immunoassay. Results: The evaluation of HIV-1 RT inhibitory activity revealed that seven compounds have significantly lower Iota C-50 values than nevirapine (0.3 mu Mu). It was observed that the activity of compounds depends not only on the nature of substituent and it position in benzothiazole ring but also on the nature and position of substituents in benzene ring. Conclusion: Twenty four of the tested compounds exhibited inhibitory action lower than 4 mu Mu. Seven of them showed better activity than nevirapine, while three of the compounds exhibited IC50 values lower than 5 nM. Two compounds 9 and 10 exhibited very good inhibitory activity with IC50 1 nM.

Non Nucleoside Reverse Transcriptase Inhibitors, Molecular Docking Studies and Antitubercular Activity of Thiazolidin-4-one Derivatives

Background: Management of Co-existence of Acquired immunodeficiency syndrome and Tuberculosis has become a global challenge due to the emergence of resistant strains and pill burden. Objective: Hence the aim of the present work was to design and evaluate compounds for their dual activity on HIV-1 and Tuberculosis (TB). Methods: A series of seven, novel Thiazolidin-4-one derivatives were synthesized and evaluated for their anti-HIV and anti-tubercular activity along with Molecular docking studies. All the seven compounds displayed promising activity against the replication of HIV-1 in cell-based assays.

The binding affinity of all the designed compounds for HIV-RT and Mycobacterium tuberculosis Enol Reductase (MTB InhA) was gauged by molecular docking studies which revealed crucial thermodynamic interactions governing their binding. Results: The CC50 values for the test compounds were in the range of, 15.08-34.9 mu g/ml, while the IC50 values were in the range of 16.1-27.13(UG(070); X4) and 12.03-23.64 (VB59; R5) mu g/ml. The control drug Nevirapine (NVP) exhibited CC50 value of 77.13 mu g/ml and IC50 value of 0.03 mu g/ml. Amongst all these compounds, compound number 3 showed significant activity with a TI value of 2.167 and 2.678 against the HIV-1 X4 and the R5 tropic virus respectively. In anti-mycobacterial screening, the compounds proved effective in inhibiting the growth of both log phase and starved MTB cultures. Conclusion: Compound 3 has been found to be active against HIV-1 as well as MTB.
