Tryptophan metabolism has been recognized as an important mechanism in immune tolerance. Indoleamine 2,3-dioxygenase plays a key role in local tryptophan metabolism via the kynurenine pathway and has emerged as a therapeutic target for cancer immunotherapy. Our prior study identified phenyl benzenesulfonyl hydrazide 2 as a potent in vitro (though not in vivo) inhibitor of indoleamine 2,3-dioxygenase. Further lead optimization to improve in vitro potencies and pharmacokinetic profiles resulted in N′-(4-bromophenyl)-2-oxo-2,3-dihydro-1H-indole-5-sulfonyl hydrazide 40, which demonstrated 59% oral bioavailability and 73% of tumor growth delay without apparent body weight loss in the murine CT26 syngeneic model, after oral administration of 400 mg/kg. Accordingly, 40, is proposed as a potential drug lead worthy of advanced preclinical evaluation.

The invention concerns novel, pharmaceutically useful, benzheterocyclyl sulphones of the formula I: STR1 in which ring A may bear optional halogeno, (1-4C)alkyl or fluoro(1-4C)alkyl substituents; X is oxygen, or a group of the formula --S(O)n -- or --NR1 -- in which n is zero, 1 or 2 and R1 is hydrogen, (1-4C)alkyl, (1-6C)alkanoyl, benzoyl or phenyl(1-4C)alkyl, the last two optionally substituted; Y is various linking groups defined hereinafter, such as ethylene or trimethylene; and in which the group --SO2 CH2 NO2 is located at position a, b or c in ring A; together with the non-toxic thereof. Other aspects of the invention include the production of the novel compounds by analogy processes and pharmaceutical compositions of the novel compounds for use in the treatment of diabetic complications.
