Sulphamethoxazole combined with 2-4-diamino-pyrimidines in the treatment of gonorrhoea.

Trimethoprim-sulphamethoxazole in gonorrhoea. A comparison with privampicillin combined with probenecid.

419 patients with uncomplicated gonorrhoea were treated with sulphamethoxazole 4 g. combined with trimethoprim 0-8 g. divided into two doses with an 8-hr interval. The failure rate was 1-9 per cent. Parallel with this trial, 319 patients received pivampicillin 1-4 g. combined with probenecid 1 g,; the failure rate was 0-9 per cent. Side-effects were few, four patients in the first group and one...

Short-term treatment of gonorrhoea with intramuscular and oral forms of trimethoprim-sulphamethoxazole.

Fifty-nine male patients and 41 female patients with uncomplicated gonorrhoea were treated with an intramuscular dose of 1600 mg sulphamethoxazole plus 320 mg trimethoprim followed by an oral dose of 2400 mg sulphamethoxazole plus 480 mg trimethoprim 12 hours later. Forty-nine out of 52 male patients and 37 out of 38 female patients who were re-examined were cured. One of the men probably had a...

Co3O4/NiO@GQDs@SO3H nanocomposite as high performance catalyst for the preparation of pyrimidines

Co3O4/NiO@GQDs@SO3H nanocatalyst has been used as an effective catalystfor the preparation of 2,4-diamino-6-arylpyrimidine-5-carbonitrile derivativesthrough a three-component reaction of malononitrile, aromatic aldehydes andguanidine hydrochloride under reflux conditions in ethanol. The catalyst has beencharacterized by FT-IR, XRD, SEM, EDS, BET, TGA, XPS and VSM. Atom e...

SYNTHESIS OF 4,4'-BIS-PYRIMIDINES AND SOME RELATED BIS-FUSED PYRIMIDINES

2,2'-Disubstitutedamino-4-4'-bis-pyrimidines (3a-m) have been prepared by linking 2,4-dichloro-6-methyl-5-nitropyrimidine (1) with several diamines and subsequent reaction with suitable amines. Some of these compounds (3c and 3j) which were reduced catalitically, on treatment with nitrous acid, urea in pyridine, and boiling thionyl chloride gave the corresponding bistriazolopyrimidin (6), ...
