ICS: A61K031-445; A61K031-40; A61K031-165. APPLICATION: US 2003-713746 14 Nov 2003. DOCUMENT TYPE: Patent CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) Section cross-reference(s): 1, 63 Amide derivs. (shown as I and II; variables defined below; e.g. N-[2-((S)-3-hydroxypyrrolidin-1-yl)-(S)-1-phenylethyl]-N-methyl-2-phenyla minoacetamide (shown as III)) are disclosed. Pharmaceutical compns. contg. these compds., and methods for their use, inter alia, for treating and/or preventing gastrointestinal disorders, pain, and pruritus (no data) are also disclosed. Although the methods of prepn. are not claimed, 36 example prepns. are included. For example, III was prepd. (45 %) by coupling of N-phenylglycine with N-[2-((S)-3-hydroxypyrrolidin-1-yl)-(S)-1-phenylethyl]-N-methylamine dihydrochloride. For I and II: R1 is H or OH; Ra is alkyl; R2 is alkyl, aryl, or aralkyl; R3 is alkyl, or R2 and R3 taken together with the atoms through which they are connected form a 4- to 8-membered heterocyclic ring; R4 is H, alkyl, cycloalkyl, alkylcycloalkyl, aryl, aralkyl, heteroaryl, or heteroarylalkyl; Z is -(CH2)oNR5R6 or -(CH2)oC(:O)NR7R8; R5 is H, alkyl, or aryl; R6 is aryl, alkaryl, -CO(NH)pR9, or -SO2R9, provided that at least one of R5 and R6 is other than aryl; R7 is H or alkyl; R8 is alkyl, aryl, aralkyl, alkaryl, heteroaryl, heteroarylalkyl, cycloalkyl or cycloalkylalkyl; R9 is alkyl, cycloalkyl, alkylcycloalkyl, aryl, aralkyl, heteroaryl, or heteroarylalkyl; m is the integer 1, 2, or 3; n is the integer 1, 2, or 3; o is the integer 0, 1, 2, or 3; p is the integer 0 or 1; and the quantity (m+n) is an integer 2-5. Compds. in all the examples showed k receptor affinity (K1) <10 mM. For example, III had a Ki = 0.17 nM against the human k receptor with >100′ selectivity vs. the human m and d receptors and was an agonist with an EC50 = 0.05 nM. It exhibited a % A = 96.2% at a dose of 300 mg, i.paw in the in vivo formalin-induced nociception assay. This compd. also blocked the action of HOAc-induced writhing when administered s.c. with an ED50 = 0.017 mg/kg.

CLASS: IC: C09K003-00. PRIORITY: US 76-744856 24 Nov 1976. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Section cross-reference(s): 25 Substituted diphenylformamidines I with R = CO2H, alkoxycarbonyl, CN, Ph, AcNH, H2NCO, or a similar group were useful as light stabilizers in plastics, dyes, etc. Thus, reaction of p-aminobenzonitrile [873-74-5] with HC(OEt)3 [122-51-0] gave I (R = CN) [67126-84-5]. Exposure to UV light during 32 h caused the degrdn. of 4% of a sample of I (R = CN) (in iso-PrOH), compared with 100% degrdn. of 2-hydroxy-4-methoxybenzophenone. ..
