Peptide analogues with renininhibiting activity.

摘要

Peptide analogues of formula (I) and their salts are new. R1-Z-NR2-CHR3-CR4-(CH2)o-(CR5)t- (CH2)v-CE-CwH2w-R6 (I) R1 = H, -CO-CmH2m-O-R7, -CO-O-CmH2m-R7, -CO-CmH2m-R7, -SO2-R7, -CO-CmH2m-NR8R9, -CO-CmH2m-NH-C(=NH)-NH-R10, -CO-CmH2m-COOR8, -CO-CmH2m-SO3R8 or -CO-CrH2r-L(R7-CpH2p)-CnH2n-(V)y- (T)s-CmH2m-R11. Z = 0-4 gps. selected from Abu, Ada, Ala, betaAla, Arg, Asn, Asp, Bia, Cal, Dab, Gln, Glu, Gly, His, N(im)-A-His, HpH, Ile, Isoser, Leu, tert-Leu, Lys, Mal, Met, alphaNal, betaNal, Nbg, Nle, Nva, Orn, Phe, Pia, Pro, Pya, Ser, Thr, Tia, Tic, Trp, Tyr or Val. R2, R8, R9 = H or A, where A = 1-8C alkyl. R3, R7, R11 = H, A, Ar, Ar-alkyl, Het opt. substd. Het-alkyl, 4-11C cycloalkyl-alkyl, 7-14C bi- or tricycloalkyl, or 8-18C bi- or tricycloalkylalkyl. R11 also = -OR8, -NR8R9, -COOR8 or A3N+An-. R4 = (H,R12) or = O. R2 and R12 may together form -CR8R13-O-. R5 = (H,H), (H,OH), (HOAc), (H,OSiR14R15R16), (H,tetrahydro-2-pyranyloxy), or =O. R6 = H, A, CN, CH=Y, COOR7, COR7, CONR8R9, NR8R9, NH-COOR7, NH-COR7, NH-CONR8R9, NH-SO2NR8R9, OH, OR14, OAc, OSO2R14, OSiR14R15R16, tetrahydro-2-pyranyloxy, Cl, Br, I, SR7, SOR7 or SO2RSO2R7. E = -S(O)b-CH2-(CR17)c-CH2-S(O)b-, where b = 0-2. c,s,t,v,y = 0 or 1; m,n,o,p,r,w = 0-10. Two cpds. are specifically claimed, i.e. 2-((2S,3S)-3-(BOC-Phe-His-amino)-4- cyclohexyl-2-hydroxybutyl)-1,3-dithian and the corresp. -1,2,3,3-tetroxide.
