Patent ID: 8686144

Claim:
A medicament, comprising: a compound of formula (I): a tautomeric form of the compound of formula (I), a pharmaceutically acceptable salt of the compound of formula (I), or a combination thereof, wherein C is a pyrrole heterocycle or a pyrazine heterocycle, R 1 is H or an alkyl radical comprising from 1 to 6 carbon atoms, R 1 being present only when C is a pyrrole heterocycle, R 2 is H, an oxygen atom double bonded to D, a halogen atom, a 1,2-ethanedioxy group, a 1,2-ethanedithio group, a phenyl group, a benzyl group, â€”OR, â€”SR, â€”NHR, or â€”N(R) 2 , R is H or an alkyl radical comprising from 1 to 6 carbon atoms, R 3 is present only when R 2 is an oxygen atom double bonded to D, a 1,2-ethanedioxy group, or a 1,2-ethanedithio group, if R 3 is present, it is a hydrogen atom or an alkyl radical comprising from 1 to 6 carbon atoms, R 4 and R 5 are each independently a hydrogen atom or an alkyl radical comprising from 1 to 6 carbon atoms, or together are a substituted or unsubstituted aryl cycle fused with D via carbon atoms 3 and 4, R 6 and R 7 are both hydrogen atoms, or together are an aryl cycle substituted by an â€”OH group, an â€”NHRâ€² group, or both, wherein Râ€² is H or an alkyl radical comprising from 1 to 6 carbon atoms, R 8 and R 9 are both hydrogen atoms, or together are an aryl cycle substituted by an â€”OH group, an â€”NHRâ€² group, or both, wherein Râ€² is H or an alkyl radical comprising from 1 to 6 carbon atoms, and with the proviso that either R 6 and R 7 or R 8 and R 9 together is an aryl cycle substituted by â€”OH or â€”NHRâ€² or both, Râ€² is H or an alkyl radical comprising from 1 to 6 carbon atoms, wherein if R 6 and R 7 is an aryl cycle then the aryl cycle is fused with B via carbon atoms 6 and 7, and R 8 and R 9 are hydrogen atoms, and if R 8 and R 9 together is an aryl cycle then the aryl cycle of R 8 and R 9 is fused with B via carbon atoms 8 and 9, and R 6 and R 7 are hydrogen atoms; and a pharmaceutically acceptable excipient or carrier.
