Applying Screening Techniques to Two Orphan Gpcrs

In contrast, it also has a large number of understudied or orphan receptors. Pharmacological assays such as β-Arrestin recruitment assays, are one of the possible approaches for deorphanization of receptors. In this work, I applied the assay system previously mentioned to screen compounds in two orphan receptors, GRP37 and MRGPRX3. GPR37 has been primarily associated with a form of early onset Parkinsonism due to its’ expression patterns, and physiological role as substrate to ubiquitin E3, parkin. Although extensive literature regarding this receptor is available, the identification of a universally recognized ligand has not yet been possible. Two compounds were proposed as ligands, but both were met with controversy. These receptor association with Autosomal Recessive Juvenile Parkinson positions it as a very attractive drug target, and as such its’ deorphanization is a prime objective for investigators in this area. Regarding MRGPRX3 information is much scarcer. -

Theophylline Level
Lab Dept: Chemistry Test Name: THEOPHYLLINE LEVEL General Information Lab Order Codes: THEM Synonyms: Aminophylline, Theo-Dur, Slo-Bid CPT Codes: 80198 - Theophylline Test Includes: Theophylline concentration reported in mcg/mL. Logistics Test indications: Assessing and adjusting theophylline dosage for optimal therapeutic level. Assessing theophylline toxicity Theophylline is used to relax smooth muscles of the bronchial airways and pulmonary blood vessels to relieve and prevent symptoms of asthma and bronchospasm. Caffeine is a minor metabolite and is often seen in neonates taking theophylline. Peak levels are achieved in 30–90 minutes depending on the compound and type of preparation. Theophylline has a half-life of approximately 4 hours in children and adult smokers, and 8.7 hours in nonsmoking adults. Lab Testing Sections: Chemistry Referred to: Mayo Clinic Laboratories (MML Test: THEO) Phone Numbers: MIN Lab: 612-813-6280 STP Lab: 651-220-6550 Test Availability: Monday - Saturday Turnaround Time: 1 day Special Instructions: N/A Specimen Specimen Type: Blood Container: Preferred: Serum Gel (SST) Alternate: Red Top Draw Volume: 1.5 mL blood Processed Volume: 0.5 mL (Minimum: 0.25 mL) serum Collection: Routine blood collection Special Processing: Lab Staff: Centrifuge specimen within 2 hours of collection. Store and ship at refrigerated temperature. Patient Preparation: None Sample Rejection: Mislabeled or unlabeled specimen; gross hemolysis Interpretive Reference Range: Therapeutic: Bronchodilation: 8.0-20.0 mcg/mL Neonatal apnea (< or =4 weeks old): 6.0-13.0 mcg/mL Interpretation: Response to theophylline is directly proportional to the serum level. Patients usually receive the best response when the serum level is above 8.0 mcg/mL, with minimal toxicity experienced as long as the level is less than or equal to 20.0 mcg/mL Critical Values: >20.0 mcg/mL Limitations: Coadministration of cimetidine and erythromycin will significantly inhibit theophylline clearance, requiring dosagereduction. -

Effect of Theophylline and Enprofylline on Bronchial Hyperresponsiveness
Thorax: first published as 10.1136/thx.44.12.1022 on 1 December 1989. Downloaded from Thorax 1989;44:1022-1026 Effect of theophylline and enprofylline on bronchial hyperresponsiveness G H KOETER, J KRAAN, M BOORSMA, J H G JONKMAN, TH W VAN DER MARK From the Department ofPulmonology and Lung Function, University Hospital, Groningen; Pharma Bio Research, Assen; and Astra Pharmaceutica, Rijswijk, The Netherlands ABSTRACT The effect of increasing intravenous doses of theophylline and enprofylline, a new xanthine derivative, on bronchial responsiveness to methacholine was studied in eight asthmatic patients. Methacholine provocations were carried out on three days before and after increasing doses of theophylline, enprofylline, and placebo, a double blind study design being used. Methacholine responsiveness was determined as the provocative concentration of methacholine causing a fall of 20% in FEV, (PC20). The patients were characterised pharmacokinetically before the main study to provide an individual dosage scheme for each patient that would provide rapid steady state plasma concentration plateaus of 5, 10, and 15 mg/l for theophylline and 1 25, 2 5, and 3-75 mg/l for enprofylline. Dose increments in the main study were given at 90 minute intervals. FEV, showed a small progressive decrease after placebo; it remained high in relation to placebo after both drugs and this effect was dose related. Methacholine PC20 values decreased after placebo; mean values were (maximum difference 2-0 and 1 7 higher after theophylline and enprofylline than after placebo copyright. doubling doses of methacholine); the effect of both drugs was dose related. Thus enprofylline and theophylline when given intravenously cause a small dose related increase in FEV1 and methacholine PC20 when compared with placebo. -

These authors contributed equally. y Co-last authors. z Received: 22 July 2020; Accepted: 4 September 2020; Published: 8 September 2020 Abstract: The senescence process is the result of a series of factors that start from the genetic constitution interacting with epigenetic modifications induced by endogenous and environmental causes and that lead to a progressive deterioration at the cellular and functional levels. One of the main causes of aging is oxidative stress deriving from the imbalance between the production of reactive oxygen (ROS) and nitrogen (RNS) species and their scavenging through antioxidants. Xanthine oxidoreductase (XOR) activities produce uric acid, as well as reactive oxygen and nitrogen species, which all may be relevant to such equilibrium. This review analyzes XOR activity through in vitro experiments, animal studies and clinical reports, which highlight the pro-aging effects of XOR products. However, XOR activity contributes to a regular level of ROS and RNS, which appears essential for the proper functioning of many physiological pathways. This discourages the use of therapies with XOR inhibitors, unless symptomatic hyperuricemia is present. -
