Solution-phase microwave assisted parallel synthesis of N,N′-disubstituted thioureas derived from benzoic acid: Biological evaluation and molecular docking studies
摘要:
An efficient and facile microwave-assisted solution phase parallel synthesis for a 26-member library of N,N'-disubstituted thiourea analogs were accomplished successfully. The reaction time for synthesis of analogs was drastically reduced from a reported 8-12 h to only 10 min. Compounds were more than 95% pure, as characterized by modern analytical techniques, i.e. H-1 & C-13 NMR and FT-IR. The solid phase structural analysis has also been performed by single crystal XRD analysis. Synthesized compounds were preliminary screened for their in vitro urease inhibition and antifungal activity. Most of the compounds were found to be potent inhibitors of urease. However, the most significant activity was found for 11 with IC50 of 1.67 mu M. The docking scores correlate with the IC50 values of inhibitors. (C) 2013 Elsevier Masson SAS. All rights reserved.

Six new ferrocenyl guanidines were synthesized and characterized by elemental analysis, FT-IR and H-1 and C-13 NMR. Compounds 1-6 were screened for antioxidant, protein kinase inhibition, lethality of brine shrimp, and cytotoxicity against the human leukemia THP-1 cell line. The compounds demonstrated moderate to significant activities. Antioxidant activity of the synthesized compounds was evaluated by DPPH % inhibition with IC50 values. All compounds 1-6 showed notable antioxidant activity with DPPH having IC50 values between 23.2-15.1 and noteworthy brine shrimp lethality. Compound 6 demonstrated the highest cytotoxicity against brine shrimps with LC50 of 9.09 mu g/mL. Protein kinase inhibition activity showed significant hyphea formation inhibition at 100 mu g/disc with 10 to 13 mm clear zone of inhibition for the compounds 2-6. The compounds were screened for in vitro cytotoxicity using human leukemia cell line (THP-1 ATCC#TIB-202). Among all compounds, the most significant activity was demonstrated by compounds 6 and 5 with IC50 of 3.88 and 5.59 mu g/mL which was comparable with the standard 5-flourouracil and vincristine drugs.
