This invention provides novel compositions comprising substituted polyamines as acid gas scrubbing solutions and methods of using the compositions in an industrial system. The invention relates to the use of such polyamine compounds in industrial processes to remove acidic contaminants from natural and industrial fluid streams, such as natural gas, combustion gas, natural gas, synthesis gas, biogas, and other industrial fluid streams. The compositions and methods of the invention are useful for removal, absorption, or sequestration of acidic contaminants and sulfide contaminants including CO.sub.2, H.sub.2S, RSH, CS.sub.2, COS, and SO.sub.2.

A composition containing a cationic polymer obtained from a reaction product of nitrogen-containing heterocyclic compound and epihalohydrin; and a phosphorus compound. The composition can be used as a surface treatment for gold or gold alloy. The composition can seal pinholes on the surface of the gold or gold alloy.

The application relates to substituted hydantoinamides of formula (I) as ADAMTS7 antagonists, to processes for their preparation, their use alone or in combination for the treatment or prophylaxis of diseases, in particular of cardiovascular diseases, including atherosclerosis, coronary artery disease (CAD), peripheral vascular disease (PAD), arterial occlusive disease or restenosis after angioplasty. R.sup.1 is hydrogen, alkyl, cycloalkyl, heterocycloalkyl, heteroaryl or phenyl; R.sup.2 is hydrogen, cyano, halogen, alkylsulfonyl, alkyl, cycloalkyl or alkoxy; R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7 and R.sup.8 are independently hydrogen, halogen, alkyl or alkoxy; most groups being optionally substituted; with the proviso that at least one of R.sup.2, R.sup.3, R.sup.4 is H; X.sup.1, X.sup.2, X.sup.3, X.sup.4, X.sup.5 and X.sup.6 are independently N or C; with the proviso that in each ring maximal one X is N. ##STR00001##
