A compound according to the general Formula I

• wherein
• R1 is —XSO2NR5R6 or —XSO2R8;
• X is a branched or unbranched C1-4 alkylene, wherein said C1-4 alkylene optionally can be bound to R5 or R6 to form a 5- or 6-membered heterocycle;
• R5 and R6 independently of each other are selected from the group consisting of hydrogen, C1-4alkyl, hydroxy-C1-4alkyl, C3-4alkenyl, C3-8-cycloalkyl, C3-8-cycloalkyl-C1-4-alkyl, C4-7-heterocycloalkyl-C0-4alkyl, C4-7-aryl-C0-4alkyl, and C4-7-heteroaryl-C0-4alkyl;
• or
• wherein R5 and R6 together with the N-atom to which they are bound form a 5- to 8-membered heterocycloalkyl,
• wherein said cycloalkyl, heterocycloalkyl, aryl, heteroaryl or alkyl is further optionally substituted by up to 2 radicals selected from the group consisting of halo, hydroxy, aminocarbonyl, C1-4 alkyl, hydroxy-C1-4 alkyl, C1-4 alkyl-O—C1-4 alkyl, C1-4 alkyl-O—, and —NR5R6;
