2-[(Phenylthio)methyl]pyridine derivatives inhibited the dermal reverse passive Arthus reaction (RPAR) in the rat. In the same model, indomethacin was inactive, and hydrocortisone was active. Compounds Ia-d also significantly reduced exudate volume and white blood cell accumulation in the pleural RPAR. This pattern of activity was similar to that of hydrocortisone and different from that of indomethacin
Novel cephalosporin derivatives possessing a bicyclic heterocycle at the 3-Position. Part I: synthesis and biological activities of 3-(Benzothiazol-2-yl)thiocephalosporin derivatives, CP0467 and related compounds
A series of cephalosporin derivatives with various bicyclic heterocycles at the C-3 position was synthesized and evaluated for antibacterial activity. Among them CP0467 (3a) showed excellent antibacterial activity against methicillin-resistant Staphylococcus aureus (MRSA) (MIC90 = 6.25 microg/mL), and extremely high affinity for the penicillin binding protein 2' of MRSA (I50 = 0.49 microg/mL). Furthermore
An aminothiazolyl- or aminothiadiazolyl-cephalosporin derivative represented by the following general formula (I) which has a condensed-ring thio group as a 3-positioned substituent group that contains a thiazolylthio group, an oxazolylthio group or a heterocyclic ring thereof as one of the ring components. The compound according to the present invention has excellent activities to inhibit growth of various bacteria, especially Gram-positive bacteria including methicillin-resistant Staphylococcus aureus (MRSA), and therefore, the antibacterial agent comprising, as an active ingredient, the inventive compound can be used as a therapeutic drug for the treatment of various bacterial infections. ##STR1##

The interactions of sodium salts of 2-mercaptobenzoxazole, 2-mercaptobenzothiazole and 2-mercaptobenzimidazole with (chloromethyl)trimethyl-, chloromethyl(dimethoxy)methylor (chloromethyl)trimethoxysilanes have been shown to result in the corresponding previously unknown (2-heterylthiomethyl)triorganylsilanes. Transetherification of (2-heteryl-thiomethyl)trimethoxysilanes with triethanolamine gives
