摘要:
Provided are novel 2-fluorophenyl propionic acid derivatives which have excellent anti-inflammatory/analgesic effects while avoiding side effects such as gastrointestinal disorders, namely 2-fluorophenyl propionic acid derivatives represented by the formula (I) below or pharmaceutically acceptable salts thereof,
[wherein, R 1 represents a hydrogen atom, a halogen atom, or a substituted or unsubstituted phenyl group, X represents -CH 2 -, -NH-, -O-, or -S-, and Y specifically represents group (II)
(wherein, Z 1 represents -CO-, -CH(OH)-, or -CH 2 -, and n represents an integer of 1 or 2.)]
摘要:
There is provided a novel loxoprofen derivative that has no side effect such as a gastrointestinal disorder and also has excellent anti-inflammatory and analgesic effects and is represented by the following formula (I) or (II):
(wherein R 1 and R 2 each represent a halogen atom or a substituted or unsubstituted phenyl group) or a pharmacologically acceptable salt thereof. In the derivative, the halogen atom is selected from a chlorine atom, a bromine atom, a fluorine atom, and an iodine atom, and a substituent of the substituted phenyl group is a halogen atom, a hydroxyl group, a substituted or unsubstituted lower alkyl group, a lower alkylthio group, a lower alkoxy group, a nitro group, an amino group, or a carboxyl group.
摘要:
A PGE1 derivative is provided which has an excellent sustained, slow-release PGE1 action. In addition, a PGE1-derivative-containing nanoparticle produced using this PGE1 derivative is provided, which effectively targets an affected site, has excellent drug slow-release properties, and has reduced side effects. This PGE1-derivative-containing nanoparticle is a nanoparticle containing a prostaglandin E1 derivative represented by the following formula (1)
(wherein n denotes an integer of 1 to 12), obtained by hydrophobicizing the prostaglandin E1 derivative with a metal ion, and reacting tne hydrophobicized prostaglandin E1 derivative with poly L-lactic acid or a poly(L-lactic acid/glycolic acid) copolymer and a poly DL- or L-lactic acid-polyethylene glycol block copolymer or a poly(DL- or L-lactic acid/glycolic acid)-polyethylene glycol block copolymer.
