Substituted n-propylamine fused heterocyclic mescaline derivatives

A compound having chemical formula (I) or (II):

• wherein, in chemical formula (I) or (II):
• is a single or double bond;
• X1, X2, and X3 are independently selected from a hydrogen atom (H), O-alkyl, acyl, N-alkyl, OH, a halogen, or NH2;
• X4 is an alkylene group or substituted alkylene group;
• R1 is a hydrogen, an alkyl group, or an oxo group, or
• R1 is joined together with R1b, together with the carbon atom to which R1 is attached and the nitrogen atom to which R1b is attached, to form an optionally substituted saturated or unsaturated 3-10 membered heterocyclic ring, and when the heterocyclic ring is unsaturated, R1a is optionally absent;
• R1a and R1b are each independently selected from an alkyl group, a hydroxylalkyl group, an optionally substituted alkyl-aryl group, or a hydrogen atom (H), or R1a and R1b are joined together, along with the nitrogen atom to which they are attached, to form a 3-10-membered optionally substituted heterocyclic ring;
• and
• R2 and R3 are each independently selected from an alkyl group, O-alkyl group, a hydrogen atom (H), or R2 and R3 are joined together with an oxygen atom together with the carbon atoms to which they are attached to form an oxirane ring.
