Synthetic repellents tend to be more effective and/or longer lasting than "natural" repellents. [1] [2]For protection against ticks and mosquito bites, the U.S. Centers for Disease Control (CDC) recommends DEET, icaridin (picaridin, KBR 3023), oil of lemon eucalyptus (OLE), para-menthane-diol (PMD), IR3535 and 2-undecanone with the caveat that higher percentages of the active ingredient ...
The blood tests checks for per- and polyfluoroalkyl substances — PFAS, a family of over 10,000 long-lasting human-made chemicals used in commercial and industrial products.
The structure-activity relationship of the drug class has been explored to a reasonable extent. The optimal substitution pattern is fairly tightly defined (i.e. N,N-diethyl on the amine nitrogen, 4-ethoxy on the benzyl ring and 5-nitro on the benzimidazole ring), but even derivatives incorporating only some of these features are still potent opioids.
