The present invention is based on the following general formula ( wherein , (atom or lower alkyl group) and salts thereof. The compound of the present invention represented by the above formula is, for example, represented by the general formula (In the formula, X, R 1 and R 3 are the same as above.) An acetic acid derivative represented by or a reactive derivative in its carboxyl group and the formula It can be obtained by reacting with 2-aminothiazole or 2-aminothiazoline represented by: For the reaction, usual acid amide formation reaction conditions are employed. For example, the compound represented by the general formula [] and the compound represented by the formula [] may be reacted in an inert solvent in the presence of an auxiliary agent such as dicyclohexylcarbodiimide, or if necessary, the compound represented by the general formula [] may be reacted with the compound represented by the formula []. Reactive derivatives such as halides such as chloride and bromite, various active esters, mixed acid anhydrides with carbonic acid, formic acid, etc. are mixed with alkali metals or The desired product can be obtained in good yield by reacting with the compound [ ] in the presence of an inorganic base such as an alkaline earth metal hydroxide, carbonate or acetate, or an organic base such as pyridine or triethylamine. Compounds in which X in the general formula [] is SO or SO 2 are prepared by preparing the corresponding compound in which X is a sulfur atom in a solvent such as water, acetic acid, chloroform, benzene, formic acid, methylene chloride, etc., in peracetic acid, perpropionic acid,
perbenzoic acid, perphthalic acid, sodium peroxide,
It can be easily obtained by reacting with a peracid or peroxide such as hydrogen peroxide. In addition, when these peracids or peroxides are liquids, they can also serve as a solvent. Among these compounds, optically active ones are D-
It can be optically resolved into the d-form, which forms a salt with camphorsulfonic acid, and the l-form, which does not form a salt. One raw material compound [ ] used in the present invention is produced, for example, by the following method. A compound in which X is an oxygen atom in the general formula [] can be obtained, for example, by reacting pyridylmethanol with an α-halogeno fatty acid in an inert solvent such as dimethylformamide or dimethylsulfoxide. In addition, in the case of a compound in which X is a sulfur atom, it can be easily obtained by reacting picolyl halide and α-mercabuto fatty acid in a solvent such as alcohol, dimethylformamide, dimethyl sulfoxide, water, or the like. The compounds of the present invention thus obtained have excellent anti-inflammatory, immunostimulatory and antitumor effects and are used as medicines. For example, in an oral administration test of carrageenan for acute hind paw edema in rats, it showed an excellent edema suppression rate as shown in Table 1. Note that the compound numbers in the table correspond to the example numbers.

Add 300 ml of water to the residue, wash once with ethyl acetate, adjust the pH to 3-4 with diluted hydrochloric acid, and extract with ethyl acetate. The extract was dehydrated over anhydrous magnesium sulfate, concentrated under reduced pressure, and the residue was recrystallized from ether-isopropyl ether to obtain 100 g of 2-(2-picolylthio)propionic acid.
