摘要:
A dipeptidyl peptidase IV inhibitor which is satisfactory in respect of activity, stability and safety and has an excellent action as a pharmaceutical agent. A compound represented by the following general formula or a pharmaceutically acceptable salt thereof: wherein R1 and R2 each represents hydrogen, an optionally substituted C1-6 alkyl group, or —COOR5 whereupon R5 represents hydrogen or an optionally substituted C1-6 alkyl group, or R1, R2, and a carbon atom together represent a 3- to 6-membered cycloalkyl group, R3 represents hydrogen or an optionally substituted C6-10 aryl group, R4represents a hydrogen or a cyano group, D represents —CONR6-, —CO— or —NR6CO—, R6 represents hydrogen or an optionally substituted C1-6 alkyl group, E represents —(CH2)m— whereupon m is 1 to 3, —CH2OCH2—, or —SCH2—, n is 0 to 3, and A represents an optionally substituted bicyclic heterocyclic group or bicyclic hydrocarbon group.
摘要:
The object of the present invention is to provide a compound having a glucokinase-activating effect.A pharmaceutical composition comprising a compound represented by the general formula (I) or a pharmaceutically acceptable salt thereof as an active ingredient: wherein X means a nitrogen atom or CR6, wherein R6 means a hydrogen atom or a halogen atom; R1 means a hydrogen atom, a C1-C6 alkyl group, a C1-C6 alkoxy group or a C1-C6 alkylthio group; R2 means a hydrogen atom or a fluorine atom; R3 means a hydrogen atom or a C1-C6 alkyl group; and one of R4 and R5 means a hydrogen atom or a C1-C6 alkyl group, and the other means a C1-C6 alkylenecarboxylic acid, a C1-C6 alkylsulfonyl group, a C1-C6 alkylcarbonyl group, or CONH2.
摘要:
The invention relates to a GLP-1 derivative including an amino acid sequence of GLP-1 (7-35) having deletion, substitution and/or addition of one or more amino acids and having Waa-(Xaa)n-Yaa (in which Waa is Arg or Lys, Xaa is Arg or Lys, n is an integer of 0 to 14, and Yaa is Arg, Arg-NH2, Lys, Lys-NH2 or Hse) added to the C-terminus of the peptide having a GLP-1 activity. These derivatives are derivatives highly absorbable via a mucous membrane. In the invention, the GLP-1 derivative can be conferred with resistance to dipeptidyl peptidase IV by substituting amino acid 8 in its GLP-1 amino acid sequence with Ser, or with resistance to trypsin by substituting amino acids 26 and 34 with Gln and Asn, respectively. The efficiency of absorption of the GLP-1 derivatives of the invention via mucous membranes can be further improved by preparing a composition using a charge-regulated fat emulsion regulated to be negatively charged thereon.
