N,N-Diethyl-2-phenylacetamide

N, N-DIETHYL-2-PHENYLACETAMIDE is a safe and effective, low-cost and broad-spectrum repellent for personal protection against Hematophagous arthropods1. It has repellent activity against hematophagous insects including mosquitoes, black flies, horse flies, muscoid flies, rat fleas, and ticks, as well as land leeches and cockroaches.As an Insect repellents, it exert its effects through interactions with Ors (odorant receptors) and GRs (gustatory receptor neuron (GRN)) in mosquitoes. However, the detailed mechanism of action remains inconclusive.

When rats are exposed to whole-body attack by diethylphenylacetamide (DEPA), DEPA enters the systemic circulation when it is inhaled, and crosses air lung and lung blood barriers to be biodegraded and excreted. DEPA is converted by dealkylation and hydrolysis to the two acetamides, ethylphenylacetamide (EPA) and phenylacetamide (PA), and to phenylacetic acid (PhAA) which are excreted and identified as urinary metabolites.
