The polymer of formula A is an N-disubstituted amino acetamino aldehyde derivative. Experimental results have shown that the modified rhNGF has a higher in vivo plasma concentration and a longer in vivo half-life than when the rhNGF is not modified or is modified by monomethoxy polyglycol, and that the modified rhNGF preserves the original activity of the unmodified rhNGF. Moreover, the method of preparing the modified rhNGF is low-cost, and the modified products are highly consistent.
