million people worldwide and is treated with just one
broad-spectrum antiparasitic drug (praziquantel). Alternative
drugs are needed in the event of emerging praziquantel resistance
or treatment failure. One promising lead that has shown efficacy
in animal models and a human clinical trial is the benzodiazepine
meclonazepam, discovered by Roche in the 1970s. Meclonazepam was
not brought to market because of dose-limiting sedative side
effects. However, the human target of meclonazepam that causes
sedation (GABAARs) is not orthologous to the parasite targets
that cause worm death. Therefore, we were interested in whether
the structure of meclonazepam could be modified to produce
antiparasitic benzodiazepines that do not cause host sedation. We
synthesized 18 meclonazepam derivatives with modifications at
different positions on the benzodiazepine ring system and tested
them for in vitro antiparasitic activity. This identified five
compounds that progressed to in vivo screening in a murine model,
two of which cured parasite infections with comparable potency to
meclonazepam. When these two compounds were administered to mice
that were run on the rotarod test, both were less sedating than
meclonazepam. These findings demonstrate the proof of concept
that meclonazepam analogs can be designed with an improved
therapeutic index and point to the C3 position of the
benzodiazepine ring system as a logical site for further
structure-activity exploration to further optimize this chemical
series.",

economically impactful nematode parasites of commercial poultry.
These infections rarely cause clinical disease, but reduction in
feed conversion efficiency is detected. To determine if feed
conversion efficiency reductions correlate with any physiological
measures independent of clinical disease, we determined if
ascarid infections correlate with changes in the weights of the
small intestine, liver, or total animal weight (quantitative
measures of animal health). No correlation between parasite
burden and these metrics were observed, supporting the concept
that feed conversion is the only production metric impacted by
ascarid infections.",

<code>Antiparasitic screening </code> We offer a range of powerful high-content antiparasitic and anthelmintic screening assays using phenotyping pipelines and software developed in our laboratory. We currently offer in vitro screening assays for insect and soil-transmitted helminths of veterinary, agricultural, and human health relevance. We provide parallel multivariate screening of the model nematode *C. elegans*. Our screening platforms are scalable and provide multivariate readouts of drug action and kinetics. The deliverables for each assay will include an overview of QC data and processing of image data into informatives plots. All raw data will be retained for a year post delivery.

<code>Antiparasitic target assays</code> We offer additional services to help identify antiparasitic targets and guide structure-activity relationship studies, including procurement or creation of transgenic *C. elegans* strains for comparative phenotypic screening, forward genetic screens to identify mutations that alter drug responses, production of tissues for drug target engagement assays, and other customized deliverables.

<code>Assay pricing</code> Contact us for assay menus and pricing. Pricing will depend on the method of parasite rearing or procurement, the format and nature of drugs or chemicals provided, or other custom modifications of core experimental protocols or analysis pipelines.

In vitro assays:
- Filarial parasites: Dog heartworm (mf, L3, and L4), Brugia (adult males and females)
- Gastrointestinal nematodes: *Haemonchus contortus* (larval assasys)
- Model nematodes: *C. elegans*

We expect to have pipelines for in vivo anthelmintic efficacy and in vitro ectoparasiticide testing within the next year.
