Abstract:
Opioids can be classified according to their mode of synthesis into alkaloids, semi-synthetic and synthetic compounds.There are three classical receptors (DOP, KOP and MOP). The novel NOP receptor is considered to be a non-opioid branch of the opioid receptor family.Opioids can either act as agonists, antagonists or partial agonists at these receptors.Opioid agonists bind to G-protein coupled receptors to cause cellular hyperpolarisation.MOP receptor agonists act in the central and peripheral nervous system to elicit analgesia.

Basicity of Aliphatic Amines
To measure the basicity of amines, two conventions are generally used. The first defines Kb as the basicity constant for the deprotonation reaction of water by the amine, as presented in Figure 1. Conventionally, lower Kb indicates higher...
