产品描述

(Rac)-Dobutamine-d6 hydrochloride is a labelled racemic Dobutamine hydrochloride. Dobutamine hydrochloride is a synthetic catecholamine that acts on α1-AR, β1-AR, β2-AR (α-1, β-1 andβ-2 adrenoceptors). Dobutamine hydrochloride is a selective β1-AR agonist, relatively weak activity at α1-AR and β2-AR. Dobutamine hydrochloride can increase cardiac output and correct hypoperfusion[1][2][3][4].

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs[1].

Ractopamine Residues in Beef Cattle Hair During and After Treatment

J Anal Toxicol 2016 Mar;40(2):153-8.PMID:26662353DOI:10.1093/jat/bkv135.

The objective of the present study was to assess the accumulation of ractopamine (rac) residues in hair of Chinese Simmental beef cattle following exposure to two doses of rac for 28 days. Six male cattle were orally administered with rac hydrochloride at a dose of 0.67 mg/kg body weight/day (low-dose group, n = 3) and 2.01 mg/kg body weight/day (high-dose group, n = 3). The results suggested that rac was obviously accumulated in hair, with a concentration of 5.57 ± 0.66 ng/g (white hair) and 13.67 ± 2.73 ng/g (red hair) in the low-dose group on Day 1 of treatment, respectively. In red hair, the peak concentrations of rac were 5619.38 ± 2156.84 ng/g (low-dose group) and 6908.3 ± 1177.62 ng/g (high-dose group) on Day 14 of treatment, and then decreased slowly. In white hair, the highest concentrations of rac were 3387.38 ± 1620.87 ng/g (low-dose group) on Day 14 of withdraw and 9621.72 ± 1497.65 ng/g (high-dose group) on Day 28 of treatment. The concentration of rac in old hair was higher than that in new hair. No significant differences in rac concentrations were obtained among dosage, hair color and old versus new hair (P > 0.05). The results indicated that ractopamine is significantly accumulated in red and white hair of Chinese Simmental beef cattle, which can be used as a matrix to assess the presence of rac residues.

Ractopamine hydrochloride induces behavioral alterations and oxidative status imbalance in zebrafish

J Toxicol Environ Health A 2018;81(7):194-201.PMID:29405861DOI:10.1080/15287394.2018.1434848.

The occurrence of ractopamine (rac) hydrochloride in water bodies is of significant concern due to its ecological impacts and toxicity to humans. rac hydrochloride is a β-adrenergic agonist drug used as a feed additive to (1) improve feed efficiency, (2) rate of weight gain, and (3) increase carcass leanness in animals raised for their meat. This drug is excreted by animals in urine and introduced into the environment affecting nontarget organisms including fish. In wastewater released from farms, rac concentrations were detected from 0.124 µg/L to 30.1 µg/L, and in levels ranging from 1.3 × 10-5 to 5.4 × 10-4 μg/L in watersheds. The aim of this study was to examine the effects of exposure to rac at 0.1, 0.2, 0.85, 8.5, or 85 µg/L dissolved in water on behavior and oxidative status in adult zebrafish. At 0.85 µg/L, rac treatment increased exploratory behavior of zebrafish; while at 8.5 µg/L, decreased locomotor and exploratory activities were noted. With respect to oxidative stress biomarkers, results showed that rac at 0.2 µg/L induced lipid peroxidation and elevated total thiol content in zebrafish brain. All drug tested concentrations produced a fall in nonprotein thiol content. Finally, rac at 0.85, 8.5, or 85 µg/L increased catalase enzyme activity. Our results demonstrated that the exposure to rac induced behavioral alterations and oxidative stress in zebrafish.

Meat quality of swine supplemented with ractopamine under commercial conditions in Brazil

J Anim Sci 2012 Dec;90(12):4604-10.PMID:23100577DOI:10.2527/jas.2012-5102.

Commercial crossbred barrows and gilts (n = 340) were used to study the effects of different dietary inclusions of ractopamine hydrochloride (rac) on quality of LM and semimembranosus muscle (SM). Pigs were blocked by BW (107.3 ± 0.76 kg) and allotted to gender-specific pens (10 to 12 pigs/pen), and within blocks, pens of barrows or gilts (10 pens/treatment) were randomly assigned to 1 of 3 dietary rac inclusions (0, 5, or 10 mg/kg) fed during the last 28 d before slaughter. Initial (45-min) and ultimate (24-h) pH and temperature were measured in LM and SM. Visual and instrumental [lightness (L*), redness (a*), and yellowness (b*) values] color as well as drip loss percentages were measured in both muscles after the 24-h chilling period at 1 to 4 °C. The LM was also evaluated for marbling, and samples of the LM were used to measure intramuscular fat (IMF) content, cooking losses, and Warner-Bratzler shear force (WBSF). Pork quality characteristics of the LM (P ≥ 0.227) and SM (P ≥ 0.082) did not differ between barrows and gilts. Furthermore, neither pH nor temperature of the LM (P ≥ 0.164) or SM (P ≥ 0.284) was affected by feeding pigs rac. The LM from pigs fed 10 mg/kg of rac received lesser (P = 0.032) subjective color scores than LM from pigs fed 0 and 5 mg/kg of rac, and LM from pigs fed 10 mg/kg of rac was less (P = 0.037) red than LM from pigs fed 0 mg/kg of rac. In addition, SM from pigs fed 10 mg/kg of rac had lesser (P ≤ 0.015) a* and b* values than pork from control-fed pigs; however, L* values for LM and SM were not (P ≥ 0.081) affected by dietary rac. Drip loss percentages of the LM were similar (P = 0.815) among rac treatments, but the SM from RAC-fed pigs had smaller (P = 0.020) drip loss percentages than SM from pigs fed 0 mg/kg of rac. Marbling scores and IMF content of the LM did not (P ≥ 0.133) differ among rac treatments; however, WBSF values were greater (P = 0.005) for LM chops from pigs fed 10 mg/kg than chops from pigs fed 0 and 5 mg/kg of rac. Even though feeding barrows and gilts 10 mg/kg of dietary rac reduced (P = 0.050) cooking losses of LM chops compared with feeding 5 mg/kg of rac, including 10 mg/kg of rac in the diet of finishing pigs reduced pork tenderness. Therefore, results from this study support the recommendation that including 5 mg/kg of rac in finishing diets should improve live pig performance without detrimental effects on fresh pork quality and cooked pork palatability.

Effects of ractopamine hydrochloride on nutrient digestibility and nitrogen excretion of finishing beef cattle

Transl Anim Sci 2021 Mar 7;5(2):txab036.PMID:34853827DOI:10.1093/tas/txab036.

The objective was to quantify the effects of the beta-adrenergic agonist (β-AA) ractopamine hydrochloride (Actogain, Zoetis, Parsippany, NJ) on nitrogen excretion and nutrient digestibility in feedlot cattle. In experiment 1, 12 Simmental × Angus steers were blocked by bodyweight (531 ± 16 kg) and used in a randomized complete block design. Dietary treatments included: 1) a control without β-AA (CON) or 2) 400 mg/steer/d ractopamine hydrochloride (rac) for 35 d before slaughter. Diets contained (DM basis) 55% dry-rolled corn, 20% corn silage, 15% modified wet distillers grains with soluble, and 10% supplement. For each block, total collection of feed, orts, feces, and urine were conducted for two 5 d sampling periods during week 2 and 4 of rac supplementation. No interaction (P > 0.21) between treatment and collection period was observed for any parameter evaluated. Dietary treatment had no effect (P = 0.51) on DMI, but rac had decreased fecal DM output (P = 0.04) compared with CON. Thus, rac had greater apparent total tract DM digestibility (77.2 vs. 73.5%; P < 0.01), N digestibility (72.4 vs. 69.4%; P = 0.01), and NDF digestibility (65.6 vs. 60.2%; P < 0.01) than CON. Although treatment did not affect nitrogen intake (P = 0.52), rac tended to reduce total nitrogen excretion (113.3 vs. 126.7 g/d; P = 0.10) compared with CON due to a tendency for decreased fecal nitrogen output (53.9 vs. 61.3 g/d; P = 0.10). However, dietary treatment had no effect (P = 0.53) on urinary nitrogen output or percentage of urinary nitrogen excreted as urea (P = 0.28). Experiment 2 was an in vitro experiment conducted to validate the effects of rac on nutrient digestibility using Simmental × Angus heifers (451 ± 50 kg). Rumen fluid was collected individually by stomach tube from CON- (n = 9) and RAC-fed (n = 10) heifers to inoculate bottles containing a CON or RAC-containing substrate in a split-plot design. No interaction between rumen fluid source and in vitro substrate was observed. Greater IVDMD (P = 0.01) was observed in rumen fluid from RAC-fed heifers compared with rumen fluid from CON-fed heifers. The inclusion of rac in the in vitro substrate increased IVDMD (P < 0.01). Overall, feeding rac increased microbial digestion of the dry-rolled corn-based finishing diet to increase total tract dry mater digestion by 5% and reduce nitrogen excretion by 10.6% in the 35 d period prior to slaughter.
