The present invention provides methods of forming hydrogen sulfide. The methods include contacting a precursor compound with an unmasking agent; wherein the precursor compound comprises a hydrogen sulfide releasing moiety and a masked nucleophile; and wherein the contacting is conducted under conditions sufficient for cyclization of the precursor compound via lactone or lactam formation; thereby releasing hydrogen sulfide from the precursor compound. Hydrogen sulfide precursor compounds according to Formula I are also described, as well as methods for treating diseases and conditions using hydrogen sulfide precursors.

A new class of antibiotics, namely, mercaptoacetophenone aminohydrazones, their analogues, their method of preparation, their salts, and their use in cases of bacterial infections, either alone or with other compounds.

The present invention relates to a process for preparing sulfuric diamides of the general formula I
R.sup.1R.sup.2NS(O).sub.2NH.sub.2(I)
in which R.sup.1 and R.sup.2 are each independently a primary alkyl radical having from 1 to 8 carbon atoms, a secondary alkyl radical having from 3 to 8 carbon atoms or a cycloalkyl radical having from 5 to 8 carbon atoms, or, together with the nitrogen atom, form a 5- to 8-membered, saturated nitrogen heterocycle which, as well as the nitrogen atom, may have a further heteroatom selected from O and S as a ring member, where the nitrogen heterocycle is unsubstituted or may have 1, 2, 3 or 4 alkyl groups having in each case from 1 to 4 carbon atoms as substituents. The process comprises the following steps: i) the reaction of a secondary amine of the formula II
R.sup.1R.sup.2NH(II) in which R.sup.1 and R.sup.2 are each as defined above with sulfuryl chloride in an inert solvent, especially an aromatic solvent, in the presence of a tertiary amine to give a sulfamoyl chloride of the formula III
R.sup.1R.sup.2NS(O).sub.2Cl(III) in which R.sup.1 and R.sup.2 are each as defined above, and ii) reaction of the sulfamoyl chloride of the formula III obtained in step i) with ammonia,
the sulfamoyl chloride of the formula III being used in step ii) in the form of the solution obtained in step i) in the inert solvent, especially the aromatic solvent.
