The present invention relates to novel cephalosporin derivatives. Various Cefem derivatives have been developed as antibacterial agents, and it was discovered that a derivative with a dipeptide bonded to the 7-position amino group of the Cefem skeleton exhibits strong antibacterial activity. The present invention was completed based on the discovery that a compound with stronger antibacterial activity can be obtained by converting the amino group of the terminal amino acid of a dipeptide into an amidino group, guanidino group, cyclic guanidino group, etc. The compound of the present invention is represented by the following general formula (). In the formula, R 1 and R 2 represent H or a lower alkyl group such as methyl, ethyl, propyl, or R 1
and R 2 represents an unsubstituted alkylene group, and R 3 and R 4 represent H. n represents 1, and m represents 0 or 1. Z represents an unsubstituted alkylene group such as methylene, ethylene or propylene. R 5 is a heteroatom-containing five-membered ring which may be substituted with lower alkyl or substituted amino lower alkyl groups, such as tetrazole or triazole such as 1-methyl-1H-tetrazole and 1-dimethylaminoethyl-1H-tetrazole. When m represents O, it means that the part in parentheses does not exist and the parts before and after it are directly combined. Various methods can be considered for producing the compound () of the present invention, for example, the formula 7β-[2-amino-2-(2-aminothiazol-4-yl)acetamide]-3-
Heterocyclic thiomethyl-3-cephem-4-carboxylic acid may be reacted with an acid chloride such as acetic acid or propionic acid substituted with an amidino group, a guanidino group, a cyclic guanidino group, etc. in the presence of a deoxidizing agent. In one example, the hydrochloride of amidinoacetic acid is isolated as the acid chloride with phosphorus pentachloride in dichloromethane. After the compound () is trimethylsilylated in acetonitrile at room temperature by adding N,O-bis(trimethylsilyl)acetamide, a base such as propylene oxide or triethylamine is added as a deoxidizing agent and the mixture is cooled. −5° to 10° to this reaction solution
℃, preferably 0° to 5°C, add the initially obtained acid chloride hydrochloride of amidinoacetic acid in several portions.
Stir for 2 hours. The reaction solution was then further heated at room temperature.
Allow to react for 0.5-1 hour. After the reaction, a water-containing solvent such as water-tetrahydrofuran is added to remove the trimethylsilyl group, and then the solvent is distilled off. The target compound can be obtained by adding a solvent such as alcohol to the concentrated residue to precipitate crude crystals, or by separating and purifying the concentrated residue as it is by column chromatography using a suitable resin, such as Amberlite XAD. can. Depending on the carbon atom to which the 2-aminothiazole group is bonded and the type of Z, the cephalosporin derivative of the present invention produced in this manner may be an asymmetric carbon atom, and thus several types of optically active forms may be produced. . It is convenient to obtain these optically active forms by a manufacturing method using suitable optically active raw materials, and it is generally preferable to use the D form from the viewpoint of effectiveness. Also, 2-aminothiazole-4-
Racemic form of yl-glycine may be used, but
From the viewpoint of effectiveness, optically active forms, particularly D forms, are preferred. The compound of the present invention has a broad antibacterial spectrum and exhibits high antibacterial activity, but has particularly strong antibacterial activity against Proteus vulgaris, Enterobacter cloacae, Enterobacter erogenes, Serratia, and Marcetuscens, which are resistant to conventional cephem compounds. It also exhibits antibacterial activity against non-glucose-fermenting Gram-negative bacilli, Streptococcus and Fuecalis, which are highly resistant to commonly used β-lactam antibiotics, with the exception of Pseudomonas enaginosa. The antibacterial activity of a series of compounds of the present invention was compared with that of a known representative cefem compound, cefazolin, and the minimum inhibitory concentration (MIC μg/ml: bacterial mass 10 6 /
ml) as shown in the table below.

Add 2 ml of molar chloroform solution to perform trimethylsilylation, and then add 0.15 ml of propylene oxide. To this was added 151 mg of DL-2-amidinopropionic acid chloride hydrochloride with stirring under ice cooling, and the mixture was stirred at the same temperature for 3 hours. A mixture of 5 ml of water and 5 ml of tetrahydrofuran was added to the reaction solution, and the organic solvent was distilled off under reduced pressure. After extracting the remaining aqueous layer with ethyl acetate, the aqueous layer was purified by passing it through an Amberlite XAD column to obtain 7β-[DL-2-(DL-2-amidinopropionamide)-2-(2-aminothiazole). −
