Methisazone has been described as being used in prophylaxis since at least 1965.[2][3]

Synthesis

Methisazone synthesis: Bauer, Sadler, Br. J. Pharmacol. 15, 101 (1960); GB 975357 (1964 to Wellcome Foundation).

When isatin is treated with sodium hydride and methyl iodide, the acidic hydrogen is alkylated to product 2. Then, reaction of the ketone carbonyl with thiosemicarbazide (3) leads to methisazone (4).
