Follow my logic.

Homovanillic acid (HVA) a common metabolite of dopamine and oter 

The vanilloid receptor 1 (VR1) or capcaicin receptor, it mediates 
apoptosis in some cases.

Esters of homovanillic acid can be potent VR1 receptor agonists
3-Acyloxy-2-phenalkylpropyl amides and esters of homovanillic acid as 
novel vanilloid receptor agonists.
Bioorg Med Chem Lett. 1999 Oct 18;9(20):2909-14. 

Could it not be possible that HVA has agonistic properties on the VR1 
receptor? I mean, look at the two molecules, apart from the hyrdophic 
chain, HVA and capcaicin look very similar in regards to charge 
distribution. Might explain why dopaminergic neurons are always so damn 

I don't know, just the musing of an undergraduate.
