Patent number: 10757938
Abstract: The present invention relates to N-acylimino compound of formula (I): wherein X is O or S, in particular O; m is an integer selected from 0, 1, 2, 3, 4, 5 or 6; Het is a 5 or 6 membered carbon-bound or nitrogen-bound heterocyclic ring, W1-W2-W3-W4 represents a carbon chain group connected to N and C?N, and thus forming a saturated, unsaturated, or partially unsaturated 5 or 6 membered nitrogen containing heterocycle, wherein W1, W2, W3 and W4 each individually represent CRvRw, R1, R2 may be hydrogen, halogen, etc. R3 may be hydrogen, halogen, CN, C1-C6-alkyl, etc. R4a, R4b if present, may be hydrogen, halogen, C1-C6-alkyl, etc. R5 may be hydrogen, halogen, C1-C6-alkyl, C1-C6-alkenyl, C1-C6-alkinyl, C3-C8-cycloalkyl, S(O)nNR9aR9b, NR9aR9b, C(?O)OR8, C(?O)NR9aR9b, C(?S)NR9aR9b, C(?O)R7a, C(?S)R7a, NR9a—C(?O)R7a, NR9a—C(?S)R7a, NR9a—S(O)nR8a, a moitey Q-phenyl, where the phenyl ring is optionally substituted with one or more, e.g.

Abstract: A water-soluble peptide fluorescence material having a structure of formula (I): In formula (I), n is an integer greater than or equal to 1, R1 is independently selected from hydrogen or a nitrogen-containing functional group, R2 is independently selected from hydrogen or alkyl, and A1 is polymerized by at least one amino acid monomer and having a structure of formula (II): In formula (II), m is an integer greater than or equal to 1, and R3 in each of the amino acid monomers of A1 is independently selected from hydrogen, alkyl, aralkyl, alkylthioaalkyl, hydroxyaralky, heteroaralkyl, carboxylalkyl, or guanidinylalkyl. A2 is —OR5 or —N(R4)2, and R4 is independently selected from hydrogen, alkyl, aralkyl, alkylthioaalkyl, hydroxyaralky, heteroaralkyl, carboxylalkyl, guanidinylalkyl, monoglycosyl, biglycosyl, or oligosaccharyl, and R5 is hydrogen, alkyl, aralkyl, alkylthioaalkyl, hydroxyaralky, heteroaralkyl, carboxylalkyl, or guanidinylalkyl.
