Fused heterocyclic mescaline derivatives

A chemical compound selected from a first chemical compound having chemical formula (I), and a second chemical compound having chemical formula (II):

• wherein, in each chemical formula (I) and (II)
• R1 is an optionally substituted alkylene group having 1-3 carbon atoms or a carbonyl group (—C(═O));
• X1 and X2 are independently selected from an oxygen atom, a sulfur atom, —NH, or an N-alkyl group, and X3, X4, or X5 are independently a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, an acyl group, an amino group, an N-substituted amino group, an amide group, a substituted amide group, a substituted amido group, a hydroxy group, a cyano group, a carboxy group, a thiol group, or a thioether group, and wherein two or three of X3, X4, or X5 are a hydrogen atom;
• R3 is a methyl group, a cyano group, or a hydrogen atom;
• and
• R4 and R5 are independently selected from an alkyl group, an alkoxy group, a hydroxyalkyl group, an N-substituted amino group, an alkyl-heteroaryl group wherein the heteroaryl is optionally substituted, or a hydrogen atom, and wherein at least one of R4 and R5 is an alkyl-aryl group, wherein the aryl group is substituted by being fused to a 5 or 6 membered heterocyclic ring containing two oxygen atoms, and wherein the aryl group is additionally substituted with a halogen atom, wherein further the amino group (—NR4R5) in each of compounds of formula (I) and (II) is optionally protonated to form (—N+HR4R5), and chemical formula (I) or (II) further includes a negatively charged anion balancing the positively charged nitrogen atom.
