In similar reactions it was noted that the final tricyclic compound
could decompose into a ring-open form." We believed this to be the reason for the extra 12 peaks visible in our carbon NMR (Figure 7), but were unable to make this assertion using normal C-NMR scans.
As-Sanie noted, for dual reuptake-inhibitor antidepressants, such as tricyclic compounds
(amitriptyline, cyclobenzaprine) and serotonin-norepinephrine reuptake inhibitors, and for anticonvulsants with analgesic properties (pregabalin, gabapentin).
Targeted tricyclic compounds
(1c-6c) and (1d-7d) were synthesized by using two different strategies; firstly, single pot multicomponent reaction and the secondly, stepwise (two step) methodology, both led to minimal side reaction with high purity and trifling fuss of purification.
Xanthones are biologically active molecules belonging to a class of tricyclic compounds
characterized by a dibenzo-[gamma]-pyrone nucleus (Mazimba et al., 2013) mostly occurring in two families of higher plants, Guttiferae and Gentianaceae.
Far more effective for fibromyalgia - and most likely other central pain states as well - are dual reuptake inhibitors such as tricyclic compounds
(amitriptyline, cyclobenzaprine), serotonin-norepinephrine reuptake inhibitors (milnacipran, duloxetine), gamma hydroxybutyrate, and gabapentin.

The potential of antidepressant drugs to have cardiovascular toxicity manifested by arrhythmias and impairment of left ventricular systolic function is well known; this is found especially for tricyclic compounds
and in the elderly patients with preexisting cardiovascular diseases.
Here, we show that a) both toxic and nontoxic PAHs induce CYP1A in zebrafish embryos, acting tissue specifically through AhR1 and AhR2; b) pyrene toxicity is AhR dependent, whereas tricyclic PAH toxicity is not; c) weathered ANS crude oil causes a syndrome in zebrafish embryos that is both clearly distinct from TCDD toxicity and consistent with cardiac dysfunction expected from the most abundant tricyclic compounds; and d) the cardiovascular toxicity of weathered crude oil is independent of both AhR1 and AhR2.
In this light, it is notable that among PAHs with two to five rings, tricyclic compounds were the most potent in blocking dye coupling via gap junctions in an in vitro assay (Blaha et al.
One family of antidepressants called tricyclic compounds
may give us more information.
in which naphthalene is joined by "ortho fusion" with a hetercyclic compound.
