Title: Pharmacokinetic study of an anti‐trypanosome agent with different formulations and administration routes in mice by HPLC–MS/MS
Abstract

Previously compound12showed great anti‐trypanosome activity without toxicity in anin vivostudy. In the current study, a sensitive and rapid high‐performance liquid chromatography–tandem mass spectrometry (HPLC–MS/MS) method was developed and validated to investigate its pharmacokinetics in mouse plasma. A protein precipitation method was applied to extract the compound, and it was then separated using a Kinetex C18column with mobile phase consisting of acetonitrile–0.1% formic acid water (50:50, v/v) at a flow rate of 300 μl/min. The analytes were detected with the multiple reaction monitoring in negative electrospray ionization source for quantitative response of the compounds. Compound12was detected atm/z477.0 → 367.2, while the internal standard compound14was detected atm/z499.2 → 268.2. Inter‐ and intra‐day precision was <5.22 and 2.79% respectively, while the accuracy range was within ±9.65%. The method was successfully applied to evaluate the pharmacokinetics of compound12in mouse plasma with two formulations (20% Cremophor EL or sesame oil) and drug administration routes (oral and intraperitoneal injection). We observed a better drug serum concentration with the Cremophor formulation, and the two different drug administration routes did not show significant differences from the drug distribution.

  1. Abstract Background

    Bed bug infestations are re-emerging in the poultry industry throughout the USA. Although the impacts of bed bugs on birds’ health and welfare are poorly understood, adverse outcomes are expected, including stress, anemia, infections and lower production rates. Worker welfare is also an important consideration in commercial poultry farms. A limited number of insecticides are available for use in the complex spatial environment of commercial farms. Systemic drugs have the potential to overcome the limitations of existing pest management tactics. A recent study showed that fluralaner administered to chickens caused high levels of mortality in bed bugs.

    Methods

    To further understand the efficacy of this approach, we evaluated the pharmacokinetics of an oral solid formulation of fluralaner in 11 chickens and quantified its plasma concentration in chickens using UPLC/MS. We administered fluralaner to chickens with two doses of Bravecto®(each 0.5 mg/kg body mass) via gavage 1 week apart and evaluated its efficacy on bed bugs that fed on medicated chickens for up to 28 days post-treatment.

    Results

    Bed bugs that fed on fluralaner-treated chickens experienced > 50% mortality within 30 min of the administration of Bravecto and 100% mortality 2 days post-treatment. Mortality slowly declined to 66.6% by day 28. Fluralaner was quantifiable in the hens’ plasma for at least 28 days post-treatment. The treatment resulted in maximal plasma concentrations (Cmax) of 106.4 ng/ml around day 9.0 (Tmax), substantially higher than the LC90, the concentration needed to kill 90% of the bed bugs.

    Conclusions

    Fluralaner appears to be a promising candidate for bed bug control in poultry farms, with a treatment effect lasting at least 28 days.

    Association of plasma membrane BKCachannels with BK‐β subunits shapes their biophysical properties and physiological roles; however, functional modulation of the mitochondrial BKCachannel (mitoBKCa) by BK‐β subunits is not established.

    MitoBKCa‐α and the regulatory BK‐β1 subunit associate in mouse cardiac mitochondria.

    A large fraction of mitoBKCadisplay properties similar to that of plasma membrane BKCawhen associated with BK‐β1 (left‐shifted voltage dependence of activation,V1/2 = −55 mV, 12 µmmatrix Ca2+).

    In BK‐β1 knockout mice, cardiac mitoBKCadisplayed a lowPoand a depolarizedV1/2of activation (+47 mV at 12 µmmatrix Ca2+)

    Co‐expression of BKCawith the BK‐β1 subunit in HeLa cells doubled the density of BKCain mitochondria.

    The present study supports the view that the cardiac mitoBKCachannel is functionally modulated by the BK‐β1 subunit; proper targeting and activation of mitoBKCashapes mitochondrial Ca2+handling.

    Abstract

    Association of the plasma membrane BKCachannel with auxiliary BK‐β1–4 subunits profoundly affects the regulatory mechanisms and physiological processes in which this channel participates. However, functional association of mitochondrial BK (mitoBKCa) with regulatory subunits is unknown. We report that mitoBKCafunctionally associates with its regulatory subunit BK‐β1 in adult rodent cardiomyocytes. Cardiac mitoBKCais a calcium‐ and voltage‐activated channel that is sensitive to paxilline with a large conductance for K+of 300 pS. Additionally, mitoBKCadisplays a high open probability (Po) and voltage half‐activation (V1/2 = −55 mV,n = 7) resembling that of plasma membrane BKCawhen associated with its regulatory BK‐β1 subunit. Immunochemistry assays demonstrated an interaction between mitochondrial BKCa‐α and its BK‐β1 subunit. Mitochondria from the BK‐β1 knockout (KO) mice showed sparse mitoBKCacurrents (five patches with mitoBKCaactivity out of 28 total patches fromn = 5 different hearts), displaying a depolarizedV1/2of activation (+47 mV in 12 µmmatrix Ca2+). The reduced activity of mitoBKCawas accompanied by a high expression of BKCatranscript in the BK‐β1 KO, suggesting a lower abundance of mitoBKCachannels in this genotype. Accordingly, BK‐β1subunit increased the localization of BKDEC (i.e. the splice variant of BKCathat specifically targets mitochondria) into mitochondria by two‐fold. Importantly, both paxilline‐treated and BK‐β1 KO mitochondria displayed a more rapid Ca2+overload, featuring an early opening of the mitochondrial transition pore. We provide strong evidence that mitoBKCaassociates with its regulatory BK‐β1 subunit in cardiac mitochondria, ensuring proper targeting and activation of the mitoBKCachannel that helps to maintain mitochondrial Ca2+homeostasis.

  3. Abstract

    Nalbuphine was a semisynthetic opioid analgesic widely used in the treatment of both acute and chronic pain. We developed and validated a rapid, simple and sensitive method by ultra-performance liquid chromatography–tandem mass spectrometry (MS/MS) for the simultaneous quantitation of nalbuphine in human plasma, and we reported the pharmacokinetic features of patients during general anesthesia for abdominal surgery. Sample separation was achieved on a Kinetex Phenyl-Hexyl column (50 × 2.1 mm, 1.7 μm) after simple protein precipitation with acetonitrile. The mobile phase was composed of acetonitrile and 3 mM of ammonium acetate aqueous solution with 0.1% formic acid. Gradient elution was used in 4.5 min with a flow rate of 0.5 mL/min at 40°C. MS detection using AB Sciex QTRAP 5500 mass spectrometer was characterized by electrospray ionization for positive ions in multiple reaction monitoring mode. Quantitative ion pairs were m/z 358.4 → 340.1 for nalbuphine and m/z 340.0 → 268.3 for nalmefene, which were used as the internal standard (IS). The calibration curves showed good linearity (r2>0.99) over concentration range of 0.1–500 ng/mL. The intra-and inter-batch precisions were within 10.67%, and accuracy ranged from 94.07 to 105.34%. The IS–normalized matrix factors were 1.02–1.03 with RSD% (≤5.82%). The recoveries ranged from 101.09 to 106.30%. In conclusion, a rapid, simple, sensitive and economical analytical method was developed and validated to detect the concentration in plasma samples obtained from patients receiving nalbuphine intravenous injection and was successfully applicated to human pharmacokinetic studies of nalbuphine.

  4. Laser ablation inductively-coupled plasma mass spectrometry (LA-ICP-MS) imaging and matrix assisted laser desorption ionization mass spectrometry imaging (MALDI-MSI) are complementary methods that measure distributions of elements and biomolecules in tissue sections. Quantitative correlations of the information provided by these two imaging modalities requires that the datasets be registered in the same coordinate system, allowing for pixel-by-pixel comparisons. We describe here a computational workflow written in Python that accomplishes this registration, even for adjacent tissue sections, with accuracies within ±50 μm. The value of this registration process is demonstrated by correlating images of tissue sections from mice injected with gold nanomaterial drug delivery systems. Quantitative correlations of the nanomaterial delivery vehicle, as detected by LA-ICP-MS imaging, with biochemical changes, as detected by MALDI-MSI, provide deeper insight into how nanomaterial delivery systems influence lipid biochemistry in tissues. Moreover, the registration process allows the more precise images associated with LA-ICP-MS imaging to be leveraged to achieve improved segmentation in MALDI-MS images, resulting in the identification of lipids that are most associated with different sub-organ regions in tissues.

  5. Abstract Background

    Over the last two decades, the scale-up of vector control and changes in the first-line anti-malarial, from chloroquine (CQ) to sulfadoxine-pyrimethamine (SP) and then to artemether-lumefantrine (AL), have resulted in significant decreases in malaria burden in western Kenya. This study evaluated the long-term effects of control interventions on molecular markers ofPlasmodium falciparumdrug resistance using parasites obtained from humans and mosquitoes at discrete time points.

    Methods

    Dried blood spot samples collected in 2012 and 2017 community surveys in Asembo, Kenya were genotyped by Sanger sequencing for markers associated with resistance to SP (Pfdhfr, Pfdhps), CQ, AQ, lumefantrine (Pfcrt, Pfmdr1)and artemisinin (Pfk13).Temporal trends in the prevalence of these markers, including data from 2012 to 2017 as well as published data from 1996, 2001, 2007 from same area, were analysed. The same markers from mosquito oocysts collected in 2012 were compared with results from human blood samples.

    Results

    The prevalence of SPdhfr/dhpsquintuple mutant haplotype C50I51R59N108I164/S436G437E540A581A613increased from 19.7% in 1996 to 86.0% in 2012, while an increase in the sextuple mutant haplotype C50I51R59N108I164/H436G437E540A581A613containingPfdhps-436H was found from 10.5% in 2012 to 34.6% in 2017. ResistantPfcrt-76 T declined from 94.6% in 2007 to 18.3% in 2012 and 0.9% in 2017. MutantPfmdr1-86Y decreased across years from 74.8% in 1996 to zero in 2017, mutantPfmdr1-184F and wildPfmdr1-D1246 increased from 17.9% to 58.9% in 2007 to 55.9% and 90.1% in 2017, respectively.Pfmdr1haplotype N86F184S1034N1042D1246 increased from 11.0% in 2007 to 49.6% in 2017. No resistant mutations inPfk13were found. Prevalence ofPfdhps-436H was lower while prevalence ofPfcrt-76 T was higher in mosquitoes than in human blood samples.

    Conclusion

    This study showed an increased prevalence ofdhfr/dhpsresistant markers over 20 years with the emergenceof Pfdhps-436H mutant a decade ago in Asembo. The reversal ofPfcrtfrom CQ-resistant to CQ-sensitive genotype occurred following 19 years of CQ withdrawal. NoPfk13markers associated with artemisinin resistance were detected, but the increased haplotype ofPfmdr1N86F184S1034N1042D1246was observed. The differences in prevalence ofPfdhps-436H andPfcrt-76 T SNPs between two hosts and the role of mosquitoes in the transmission of drug resistant parasites require further investigation.
