Synthesis, antibacterial and antiviral properties of curcumin bioconjugates bearing dipeptide, fatty acids and folic acid 2009-12-09 .txt text/plain 4164 211 57 The resulting product, dissolved in anhydrous pyridine, was added dropwise to the activated folate 5 in 1:1 molar proportion in the presence of DCC and DMAP to yield the compound 10 in 26% (Scheme 4). The molecules 2, 3, 4, 6 and 8 have shown remarkable antibacterial activities with MIC ranging between 0.09 and 0.67 mM (in vitro) against gram-positive cocci (Streptococcus virudans) as well as gram-negative bacilli (Escherichia coli, Klebsiella pneumoniae, Proteus mirabeilis) bacterial strains. The compound 7, dissolved in dry pyridine (5 ml), was added dropwise to the activated folate ester 5 (286 mg, 0.51 mmol) and stirred the reaction mixture for 15 min. Compound 9 (100 mg, 0.24 mmol), dissolved in dry pyridine (6 ml), was added dropwise to the activated ester 5 (157 mg, 0.28 mmol), stirred the reaction mixture for 20 min and TEA (0.5 ml), DCC (123 mg, 0.6 mmol) and DMAP (32 mg) were further added. ./cache/cord-283128-9mbi75de.txt ./txt/cord-283128-9mbi75de.txt
