The present invention relates to compounds of Formula 4 and to antimicrobial compounds and antimicrobial compositions based on the compounds of Formula 4: wherein: X comprises sulphur or selenium; Y comprises a pharmaceutically acceptable anion; R1 and R9 are each independently hydrogen, optionally substituted alkyl, optionally substituted alkoxyl, optionally substituted amine or halogen; and R3a, R3b, R7a and R7b are each independently H or optionally substituted alkyl with the proviso that at least one of R3a or R3b and/or R7a or R7b together with the nitrogen atoms to which they are attached form an optionally substituted, optionally saturated 6 or 7-membered ring with R2 or R4 and/or R6 or R8 respectively; and R2, R4, R6, and R8 are each independently, hydrogen, optionally substituted alkyl, optionally substituted alkoxyl, or halogen, so long as at least one of R2, R4, R6 or R8 together with the atoms to which they are attached form an optionally substituted, optionally saturated 6 or 7-membered ring with R3a or R3b and/or R7b or R7a respectively; and with the proviso that the compounds are not of Formula 3a or 3b. |
