WHAT IS RCS-4 ?

RCS-4, or 1-pentyl-3-(4-methoxybenzoyl)indole, is a synthetic cannabinoid drug sold under the names SR-19,

BTM-4, or Eric-4 (later shortened to E-4), but originally, OBT-199.

RCS-4 (BTM-4, E-4, OBT-199, SR-19

RCS-4 is a potent cannabinoid receptor agonist, with EC50 values of 146 nM for human CB1 receptors, and 46 nM for

human CB2 receptors. All methoxyphenyl regioisomers, and N-butyl homologues of RCS-4 and its regioisomers also display potent agonist activities at CB1 and CB2 receptors.

RCS-4 was banned in Sweden on 1 October 2010 as a hazardous good harmful to health, after being identified as an ingredient in “herbal” synthetic cannabis products.

It was outlawed in Denmark on 11 March 2011.

In August 2011, New Zealand added not only RCS-4 but also its 1-butyl homologue, and the 2-methoxybenzoyl

isomers of both these compounds, to a temporary class drug schedule (i.e. equivalent to Class C but reviewed after 12

months, and with personal possession and use of small amounts decriminalised), which was newly created under the

Misuse of Drugs Amendment Act 2011 passed a week earlier. RCS-4 (Item No. 10645) is an analytical reference standard structurally similar to known synthetic cannabinoids.
