Add under ice-cooling N,N- diisopropylethylamine (5.4g, 41.64mmol) and Boc-D-histidine-OH (2.66g, 10.41mmol), and finally added 2- (7-azo BTA) -N, N,N ' , N'- tetramethyluronium hexafluorophosphate (HATU) (4.75g, 12.49mmol), The reaction was stirred at ice bath for 15 minutes, then go to room temperature for 3 hours. LCMS the reaction was complete, quenched with small amount of water, washed with ethyl acetate and extracted three times, the combined organic phases were washed with saturated brine, dried over anhydrous sodium sulfate, and concentrated. The resulting residue was purified by column chromatography (dichloromethane: methanol = 50: 1 to 15: 1) to afford an off-white solid, 1.21 g of, purity: 94%, yield: 27%. |

With dicyclohexyl-carbodiimide at 0℃; | Chemical synthesis of AA-CAM derivatives General procedure: The general scheme for the synthesis of AA-CAMderivatives is shown in Fig. S1 and the details ofchemical synthesis are provided in the SupplementaryMethods section. CAM [(1R,2R)-2-amino-1-(4--nitrophenyl)propane-1,3-diol)] was prepared asdescribed previously [23]. Amino acids with protectedα- and side-chain amino groups wereactivated by reaction with N-hydroxysuccinimide inthe presence of N,N′-dicyclohexylcarbodiimide at0 °C. The resulting succinimide-reactive esters wereused for the acylation of CAM in the presence ofdiisopropylethylamine as a base at room temperature.Subsequent deprotection was achieved bytreatment of the obtained amino-acid CAM derivativeswith trifluoroacetic acid and appropriate scavengers.Synthesized AA-CAM derivatives were purifiedby columnchromatography on silica gel using suitablesystems of solvents. For generating N-acetylatedvariants of AA-CAM, additional acetylation wasperformed by reacting the unprotected AA-CAMderivatives with the N-acetylsuccinimide. Purity andchemical structures of obtained compounds wereconfirmed by HPLC, LC-MS, and NMR spectroscopy(see Supplementary Methods). |
