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
Nucleophilic SN2 displacements on penicillin-6- and cephalosporin-7- triflates; 6β-iodopenicillanic acid, a new β-lactamase inhibitor

Triflate or nonaflate esters of alkyl 6α (or β) hydroxypenicillanates are substituted (with inversion) by the soft nucleophiles iodide, bromide, chloride, azide, arylselenoxide,1 thiocyanate, thiols, and thiolacids; carbon nucleophiles fail. Methoxide (hard) attacks the lactam bond, opening both rings to give a known11 1,4 thiazine. Iodide substitutes 7α-trifloxycephalosporins, giving 7β-iodocephalosporins
The Synthesis of 4-Arylsulfanyl-substituted Kainoid Analogues from trans-4-Hydroxy-l-proline

The potent neuroexcitatory activity of kainoid amino acids in the mammalian CNS places new analogues in high demand as tools for neuropharmacological research. A range of 4-arylsulfanyl-substituted kainoids has been synthesised in a parallel fashion via mesylate displacement by a number of aromatic and heteroaromatic thiolates upon (2S,3S,4R)-1-benzoyl-3-tert-butoxycarbonylmethyl-4-methanesulfo nyloxy

Reactions of thiohydrazides of oxamic acids with 17-chloro-16-formylandrosta-5,16-diene give the corresponding thiohydrazones at the formyl group. Their subsequent reactions with alkali (het)arenethiolates yield 17-het(aryl)thio derivatives, being accompanied by cyclization of the thiooxalylhydrazone fragment into a 1,3,4-thiadiazole ring.
