DOCUMENT TYPE: Journal CA Section: 63 (Pharmaceuticals) Section cross-reference(s): 7, 35 A series of water-sol. polymers I [(X = NH(CH2)n CO or (NHCH2CO)2 and n = 1-7,11] was prepd. by the copolymn. of 4-nitrophenol esters of methacryloylated w-amino acids with N-(2-hydroxypropyl)methacrylamide and contg. 3 mol.% of reactive groups.There are some commonly used reagents with their cas registry numbers 87880-83-9 and 87880-81-7 in this article. Groups degradable with chymotrypsin [9004-07-3] were bound to ends of variously long side chains by a polymeranalogous reaction with L-phenylalanine-4'-methyl-2'-nitroanilide. The dependence of the rate of degrdn. of 4-methyl-2-nitroaniline [89-62-3] on the length of the side chain was investigated. The extension of the side chain increased the rate of enzymic reaction, reaching a max. for n = 6; n = 7 or 11 decreased enzymic hydrolysis and for n = 1 and 2 degrdn. was low or almost unmeasurable. .
