A class of novel 1H-indole-3-glyoxylamides is disclosed together with the use of such indole compounds for inhibiting sPLA2 mediated release of fatty acids for treatment of conditions such as septic shock. The novel 1H-indole-3-glyoxylamides are represented by the following formula (I): (see formula I) wherein; each X is independently oxygen or sulfur; R1 is selected from groups (a), (b) and (c) where; (a) is C7-C20 alkyl, C7-C20 alkenyl, C7-C20 alkynyl, a carbocyclic radical derived from a saturated or unsaturated, substituted or unsubstituted 5 to 14 membered organic nucleus whose ring forming atoms (other than hydrogen) are solely carbon atoms, or a heterocyclic radical, derived from monocyclic or polycyclic, saturated or unsaturated, substituted or unsubstituted heterocyclic nuclei having 5 to 14 ring atoms and containing from 1 to 3 hetero atoms selected from the group consisting of nitrogen, oxygen and sulfur; (b) is a member of (a) substituted with one or more independently selected non-interfering substituents selected from the group consisting of; C1-C6 alkyl, C2-C6 alkenyl, C2-C6 alkynyl, C7-C12 aralkyl, C7-C12 alkaryl, C3-C8 cycloalkyl, C3-C8 cycloalkenyl, phenyl, tolulyl, xylenyl, biphenyl, C1-C6 alkoxy, C2-C6 alkenyloxy, C2-C6 alkynyloxy, C2-C12 alkoxyalkyl, C2-C12 alkoxyalkyloxy, C2-C12 alkylcarbonyl, C2-C12 alkylcarbonylamino, C2-C12 alkoxyamino, C2-C12 alkoxyaminocarbonyl, C2-C12 alkylamino, C1-C6 alkylthio, C2-C12 alkylthiocarbonyl, C1-C6 alkylsulfinyl, C1-C6 alkylsulfonyl, C2-C6 haloalkoxy, C1-C6 haloalkylsulfonyl, C2-C6 haloalkyl, C1-C6 hydroxyalkyl, -C(O)O(C1-C6 alkyl), -(CH2)n-O-(C1-C6 alkyl), benzyloxy, phenoxy, phenylthio, -(CONHSO2R), -CHO, amino, amidino, bromo, carbamyl, carboxyl, carbalkoxy, -(CH2)n -CO2H, chloro, cyano, cyanoguanidinyl, fluoro, guanidino, hydrazide, hydrazino, hydrazido, hydroxy, hydroxyamino, iodo, nitro, phosphono, -SO3H, thioacetal, thiocarbonyl, and carbonyl; where n is from 1 to 8; (c) is the group -(L)-R80; where, -(L)- is a divalent linking group of 1 to 12 atoms selected from carbon, hydrogen, oxygen, nitrogen, and sulfur; wherein the combination of atoms in -(L)- are selected from the group consisting of (i) carbon and hydrogen only, (ii) sulfur only, (iii) oxygen only, (iv) nitrogen and hydrogen only, (v) carbon, hydrogen, and sulfur only, and (vi) and carbon, hydrogen, and oxygen only; and where R80 is a group selected from (a) or (b); R2 is hydrogen, halo, C1-C3 alkyl, C3-C4 cycloalkyl, C3-C4 cycloalkenyl, -O-(C1-C2 alkyl), -s-(C1-C2 alkyl), or a non-interfering substituent as defined above having a total of 1 to 3 atoms other than hydrogen; R4 and R5 are independently selected from hydrogen, a non-interfering substituent as defined above, or the group, -(L a)-(acidic group); wherein -(L a)- is an acid linker having an acid linker length of 1 to 4 atoms for R4 and an acid linker length of 3 to 8 atoms for R5 provided, that at least one of R4 and R5 must be the group, -(L a)-(acidic group), said acidic group being an organic group which when attached to an indole nucleus through linking atoms, acts as a proton donor capable of hydrogen bonding; R6 and R7 are each independently selected from hydrogen, non-interfering substituents as defined above, carbocyclic radicals, carbocyclic radicals substituted with non-interfering substituents as defined above, heterocyclic radicals as defined above, and heterocyclic radicals substituted with non-interfering substituents as defined above.
