Kinase experiment: | Caspase-3 and -8 colorimetric assay kits are used according to the manufacturer’s instructions. Briefly, after treatment the cells with indicated concentration of Monepantel (0, 10 and 25 µM) for 48 and 72 h, cells are harvested, centrifuged at 250 g for 10 min. The cell pellet lysed by the addition of the lyses buffer, then incubated on ice for 10 min followed by centrifugation at 10,000 g for 5 min. The supernatant is used to start the enzymatic reaction in 96 well plates based on manufacturer protocol. Each concentration is tested in replications of 4 and each experiment is repeated twice. |
Cell experiment: | The effect of monepantel with or without other agents on cell proliferation is assessed using the sulforhodamine B (SRB) assay. Briefly, cells are seeded in 96-well plates (2500 cells/well) overnight followed by treatment with desired concentrations of Monepantel. After 72 h cells are fixed with 200 µL of 0.1% TCA, washed with tap water and stained with 100 µL of 0.4% (w/v) SRB dissolved in 1% acetic acid. Unbound dye is removed by five ishes with 1% acetic acid before air drying. Bound SRB is solubilized with 100 µL of 10 mM Tris base (pH 10.5) and the absorbance read at 570 nm. Each concentration is tested in replications of 8 and each experiment is repeated twice. Data represent mean±SEM from two independent experiments combined. |

Monepantel is organic anthelmintic, and acts as a positive allosteric modulator of a nematode-specific clade of nicotinic acetylcholine receptor (nAChR) subunits.
The metallocenyl analogues of monepantel shows nematocidal activity[1]. Monepantel (25 µM) induces accumulation of acidic vacuoles. Ovarian cancer cell lines are highly sensitive to Monepantel with IC50 values of 7.2±0.2 µM (OVCAR-3) and 10.5±0.4 μM (A2780). Monepantel (0, 10 and 25 µM) induces autophagosome formation in these cancer cell lines. Monepantel (0, 10 and 25 µM) exhibits a markedly reduced level of punctate staining indicating the suppression of phosphorylated mTOR at Ser2448. Monepantel also decreases the expression of phosphorylated Raptor at Ser792, which is one of the mTORC1 coMonepantelex members[2]. Monepantel (250 μg/mL) leads multiple ABC transporter genes higher transcription in both worm isolates. Larvae exposed to monepantel at 250 μg/mL shows an increased efflux of rhodamine-123 and a proportion of the larval population shows an ability to subsequently tolerate higher concentrations of IVM in migration assays[3].
Monepantel (10 μM) significantly increased all CYP-related activities and CYP3A24 mRNA in sheep[4].

Haemonchus contortus acetylcholine receptors of the DEG-3 subfamily and their role in sensitivity to Monepantel
PLoS Pathog 2009 Apr;5(4):e1000380.PMID:19360096DOI:PMC2662886
Gastro-intestinal nematodes in ruminants, especially Haemonchus contortus, are a global threat to sheep and cattle farming. The emergence of drug resistance, and even multi-drug resistance to the currently available classes of broad spectrum anthelmintics, further stresses the need for new drugs active against gastro-intestinal nematodes. A novel chemical class of synthetic anthelmintics, the Amino-Acetonitrile Derivatives (AADs), was recently discovered and the drug candidate AAD-1566 (Monepantel) was chosen for further development. Studies with Caenorhabditis elegans suggested that the AADs act via nicotinic acetylcholine receptors (nAChR) of the nematode-specific DEG-3 subfamily. Here we identify nAChR genes of the DEG-3 subfamily from H. contortus and investigate their role in AAD sensitivity. Using a novel in vitro selection procedure, mutant H. contortus populations of reduced sensitivity to AAD-1566 were obtained. Sequencing of full-length nAChR coding sequences from AAD-susceptible H. contortus and their AAD-1566-mutant progeny revealed 2 genes to be affected. In the gene monepantel-1 (Hco-mptl-1, formerly named Hc-acr-23H), a panel of mutations was observed exclusively in the AAD-mutant nematodes, including deletions at intron-exon boundaries that result in mis-spliced transcripts and premature stop codons. In the gene Hco-des-2H, the same 135 bp insertion in the 5' UTR created additional, out of frame start codons in 2 independent H. contortus AAD-mutants. Furthermore, the AAD mutants exhibited altered expression levels of the DEG-3 subfamily nAChR genes Hco-mptl-1, Hco-des-2H and Hco-deg-3H as quantified by real-time PCR. These results indicate that Hco-MPTL-1 and other nAChR subunits of the DEG-3 subfamily constitute a target for AAD action against H. contortus and that loss-of-function mutations in the corresponding genes may reduce the sensitivity to AADs.
