Magnetic particle spray mass spectrometry (MPS-MS), an innovative ambient ionization technique proposed by our research group, was employed to determine beta-blockers in human plasma samples. A dispersive solid phase extraction of atenolol, metoprolol, labetalol, propranolol, nadolol, and pindolol was carried out using magnetic molecularly imprinted polymer (M-MIP) particles that were attached to the tip of a metal probe, which was placed in the mass spectrometer inlet. A solvent (1% formic acid in methanol) was dispensed on the particles, and the Taylor cone was formed around them (in high voltage). The analytes were desorbed/ionized and determined by a triple quadrupole mass spectrometer. M-MIP was synthesized with oxprenolol as a pseudo-template, demonstrating good selectivity to beta-blockers compared with no-analog molecules, with an adsorption process occurring in monolayers, according to isotherm studies. Kinetic experiments indicated chemisorption as the predominant M-MIP/analyte interaction. The analytical curves were linear (R² > 0.98), and the limit of quantification was 3 µg L^-1 for all the analytes. Limits of detection ranged from 0.64 to 2.41 µg L^-1. Precisions (relative standard deviation) and accuracies (relative error) ranged from 3.95 to 21.20% and -17.05 to 18.93%, respectively. MPS-MS proved to be a simple, sensitive, and advantageous technique compared with conventional approaches. The analyses were fast, requiring no chromatographic separation and without ionic suppression. The method is aligned with green chemistry principles, requiring minimal sample, solvent, and sorbent amounts. MPS-MS successfully integrates sample preparation and ambient ionization mass spectrometry and holds great potential for application with other sorbents, samples, and analytes.

Beta-blocker carteolol and oxprenolol produce cutaneous analgesia in response to needle pinpricks in the rat

Article

作者: Chou, An-Kuo ; Chen, Yu-Wen

BACKGROUND:

This present study was undertaken to determine whether beta-blockers produce the cutaneous analgesic effect, comparing them with the long-acting local anesthetic bupivacaine.

METHODS:

Using a rat model of infiltrative cutaneous analgesia, the effect of 5 beta-blockers (oxprenolol, carteolol, butaxamine, metoprolol, and acebutolol) and bupivacaine was compared and eventually combined with epinephrine.

RESULTS:

Among 5 beta-blockers, oxprenolol exhibited the most potent and the longest duration of cutaneous analgesia. In dose-response studies, the rank order of efficacy (ED₅₀ [50% effective dose]) was bupivacaine (0.40 [0.35-0.47] μmol) > oxprenolol (2.33 [2.06-2.64] μmol) > carteolol (4.86 [4.27-5.53] μmol) (p< 0.01). Carteolol provoked a longer duration of analgesia (p< 0.01) than oxprenolol or bupivacaine on an equipotent basis (ED₂₅, ED₅₀, and ED₇₅). Adding epinephrine 1:200,000 to drug preparations (carteolol, oxprenolol, and bupivacaine) at ED₉₅ had a peripheral action in prolonging the duration of action.

CONCLUSIONS:

Oxprenolol and carteolol had greater potencies and longer durations of cutaneous analgesia than butaxamine, metoprolol, and acebutolol. Oxprenolol produced a similar duration of action when compared to bupivacaine, while carteolol had a greater duration of action than bupivacaine. Cutaneous analgesia of oxprenolol (or carteolol) plus adrenaline was greater than that of bupivacaine plus adrenaline.

Abstract:

Background:

Beta‐blockers and selected stereoisomers of beta‐blockers, like bisoprolol and S‐pindolol (ACM‐001), have been shown to be effective in preclinical cancer cachexia models. Here, we tested the efficacy of stereoisomers of oxprenolol in two preclinical models of cancer cachexia—the Yoshida AH‐130 rat model and the Lewis lung carcinoma (LLC) mouse model.

Methods and Results:

In the Yoshida AH130 hepatoma rat cancer cachexia model and compared with placebo, 50 mg/kg/d S‐oxprenolol (HR: 0.49, 95% CI: 0.28–0.85, P = 0.012) was superior to 50 mg/kg/d R‐oxprenolol (HR: 0.83, 95% CI 0.38–1.45, P = 0.51) in reducing mortality (= reaching ethical endpoints). Combination of the three doses (12.5, 25 and 50 mg/kg/d) that had a significant effect on body weight loss in the S‐oxprenolol groups vs the same combination of the R‐oxprenolol groups lead to a significantly improved survival of S‐oxprenolol vs R‐oxprenolol (HR: 1.61, 95% CI: 1.08–2.39, P = 0.0185). Interestingly, there is a clear dose dependency in S‐oxprenolol‐treated (5, 12.5, 25 and 50 mg/kg/d) groups, which was not observed in groups treated with R‐oxprenolol. A dose‐dependent attenuation of weight and lean mass loss by S‐oxprenolol was seen in the Yoshida rat model, whereas R‐oxprenolol had only had a significant effect on fat mass. S‐oxprenolol also non‐significantly reduced weight loss in the LLC model and also improved muscle function (grip strength 428 ± 25 and 539 ± 37 g/100 g body weight for placebo and S‐oxprenolol, respectively). However, there was only a minor effect on quality of life indicators food intake and spontaneous activity in the Yoshida model (25 mg/kg/S‐oxprenolol: 11.9 ± 2.5 g vs placebo: 4.9 ± 0.8 g, P = 0.013 and also vs 25 mg/kg/d R‐oxprenolol: 7.5 ± 2.6 g, P = 0.025). Both enantiomers had no effects on cardiac dimensions and function at the doses used in this study. Western blotting of proteins involved in the anabolic/catabolic homoeostasis suggest that anabolic signalling is persevered (IGF‐1 receptor, Akt) and catabolic signalling is inhibited (FXBO‐10, TRAF‐6) by S‐pindolol, but not he R‐enantiomer. Expression of glucose transporters Glut1 and Glut 4 was similar in all groups, as was AMPK.

Conclusions:

S‐oxprenolol is superior to R‐oxprenolol in cancer cachexia animal models and shows promise for a human application in cancer cachexia.

Actimed Therapeutics Announces Publication of Successful S-pindolol benzoate (ACM-001.1) Phase 1 Study in The Journal of Cachexia, Sarcopenia and Muscle

London, UK – 13th December 2024. Actimed Therapeutics Ltd (“Actimed”), a UK based clinical stage speciality pharmaceutical company focused on bringing innovation to the treatment of cancer cachexia and other muscle wasting disorders, announces that results from its Phase 1 pharmacokinetic (PK), pharmacodynamic (PD) and bioavailability study of S-pindolol benzoate (ACM-001.1) in healthy volunteers (NCT06028321) have been published in The Journal of Cachexia, Sarcopenia and Muscle. This was a two-stage Phase I study. The first stage assessed the comparative bioavailability and pharmacokinetics of a single dose of S-pindolol benzoate and two single doses of racemic pindolol. The second stage evaluated the steady-state pharmacokinetics and pharmacodynamics of multiple doses of S-pindolol benzoate in healthy volunteers. The study met all pre-defined endpoints, demonstrating that S-pindolol benzoate has predictable pharmacokinetics up to a dose of 15 mg twice daily, with low inter-subject variability after single and multiple doses. Moreover, bioavailability of S-pindolol after equivalent doses of racemic pindolol and S-pindolol benzoate was comparable, and although not a prespecified objective, formal bioequivalence margins were met. The study also showed: An absence of in vivo stereo-conversion of S-pindolol into R-pindololDose linearity and dose proportionality of S-pindolol benzoate over a wide range of doses S-pindolol benzoate was generally well tolerated A lack of food effect with S-pindolol benzoate - and an important consideration for use in cancer patients who have a high incidence of appetite loss Robin Bhattacherjee, Chief Executive Officer of Actimed Therapeutics commented “The anti-catabolic and pro-anabolic pharmacology of our lead compound S-pindolol benzoate position it as a novel and promising new therapy for cancer cachexia. These data demonstrate that S-pindolol benzoate is essentially bioequivalent to the S-pindolol present in racemic pindolol and provide strong support for the further clinical development of S-pindolol benzoate for the treatment of cancer cachexia and potentially other conditions associated with muscle wasting”. The publication may be accessed here: https://doi.org/10.1002/jcsm.13651 *** About Actimed Therapeutics Actimed Therapeutics is a clinical stage speciality pharmaceutical company focused on bringing innovation to the treatment of muscle wasting disorders to transform the care of an underserved and vulnerable patient population. The lead area of focus for Actimed is specifically in cachexia. Cachexia is a wasting disease that is associated with cancer and other serious chronic illnesses and with significant morbidity and mortality. A significant number of cancer patients suffer from cachexia1 and it is estimated that cachexia is responsible for up to 20% of all cancer deaths2. A recent meta-analysis demonstrated that cachexia was associated with an 82% higher relative risk of mortality in patients with NSCLC versus no cachexia3. Despite its prevalence and devastating clinical effects, there is no globally approved drug for the treatment or prevention of cancer-related cachexia. The lead product of Actimed, S-pindolol benzoate (ACM-001.1) targets multiple pathways that drive cachexia and has generated promising proof of concept Phase 2a clinical data in cachexia patients. Actimed is currently preparing for further clinical studies in cancer cachexia having received an Investigational New Drug (IND) approval from FDA for S-pindolol benzoate in August 2023 for the treatment of cancer cachexia. Actimed also owns the global rights to its second asset, S-oxprenolol ACM-002), which is being developed by the Company for the muscle wasting seen in amyotrophic lateral sclerosis (ALS) where loss of body mass and muscle wasting may impact survival⁴. Actimed was granted Orphan Drug Designation to S-oxprenolol for the treatment of ALS by the FDA in 2024. Actimed has licensed the global rights to develop and commercialise S-oxprenolol for cancer cachexia and any other indications outside of ALS to US company Faraday Pharmaceuticals.
