Conditions | Yield |
With dicyclohexyl-carbodiimide In dimethyl sulfoxide for 24h; Heating / reflux; Experimental Procedure EXAMPLE 8; Synthesis of Dextran 7OK Mono-carbonyl butanoic acid curcumin conjugate 2; Dextran 122 mg (3 x 10“3 mmol), Mono-carbonyl butanoic acid curcumin 16 mg (3Jx IO“4 mmol) and DCC (1, 3- dicyclohexylcarbodiimide) 10 mg (4.8χ lθ“4 mmol) were dissolved in 5.5 ml dry DMSO. The reaction was stirred for 24 h at reflux under argon The solution was filtered, dialyzed with SnakeSkin pleated dialysis tubing with Millipore water, centrifuged and lyophilized. The product resembled cotton candy and the yield was quantitative. NMR 1H (D2O), δ (ppm): compound 2,1.35-1.39 (m); 1.67 (m,); 1.78- 1.92 (bm); 2.33 (bm); 2.41-2.44 (t); 3.53-3.56 (t); 3.59-3.61 (m); 3.73-3.79 (m); 3.93- 4.02 (dd); 5.00 (d). Number of Curcumin molecules attached per polymer molecule is 22 (Estimated from UV spectroscopy using the extinction coefficient for Curcumin-COOH). | 100% |
