Abstract
Eliglustat (Cerdelga®, Genzyme Corp. Cambridge, MA, USA) is an approved drug for a non-neurological type of Gaucher disease. Herein, we describe the total synthesis of eliglustat 1 starting from readily available 1,4-benzodioxan-6-carbaldehyde via Sharpless asymmetric dihydroxylation and diastereoselective amination of chiral para-methoxycinnamyl benzyl ethers using chlorosulfonyl isocyanate as the key steps. Notably, the reaction between syn-1,2-dibenzyl ether 6 and chlorosulfonyl isocyanate in the mixture of toluene and hexane (10:1) afforded syn-1,2-amino alcohol 5 at a 62% yield with a diastereoselectivity > 20:1. This observation can be explained by competition between the SNi and the SN1 mechanisms, leading to the retention of stereochemistry.

[PMID: 33369159 PMCID: PMC8136953 DOI: 10.1002/vms3.415] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2020] [Revised: 11/03/2020] [Accepted: 12/01/2020] [Indexed: 11/09/2022] Open
Abstract
The pharmacokinetic properties and residue elimination of florfenicol (FLO) and its amine were investigated in European seabass Dicentrarchus labrax at 24°C. The trial mainly included analysis of FLO in plasma after a single dose dietary administration of 10 mg/kg and in muscle plus skin following a multiple dosing (10 mg kg-1 day-1 for 7 days) to estimate pharmacokinetics and residue depletion, respectively. The maximum plasma concentration of FLO was measured to be 1.64 μg/ml, 4 hr post administration. The elimination half-life (t1/2b ) and the area under the concentration-time curve extrapolated to infinity (AUC0-∞ ) were calculated to be 13.0 hr and 34.7 μg h-1 ml-1 , respectively. Withdrawal times of FLO and its amine were calculated to be 46.3 degree-days, indicating a fast removal from the edible tissues of treated European seabass. Overall, FLO can be considered as a potentially efficient antibacterial agent for farmed European seabass provided that additional efforts will be devoted towards its in vitro and clinical efficacy.

JOURNAL OF FISH DISEASES 2019; 42:325-334.

Abstract
Flavobacterium psychrophilum is responsible for significant economic losses in rainbow trout aquaculture. Antimicrobial treatment remains the primary means of control; however, there are limited choices available for use. The objectives of the study were therefore to determine the minimum inhibitory concentrations for erythromycin and florfenicol in selected F. psychrophilum isolates and to evaluate their clinical treatment efficacy in experimentally infected rainbow trout. All isolates tested had moderate susceptibility to florfenicol and erythromycin except one isolate, which had low susceptibility to erythromycin. Two isolates (one with moderate and one with low susceptibility to erythromycin) were used in an experimental infection trial. Rainbow trout juveniles were injected intraperitoneally with 108 cfu/fish and after mortality had begun, fish were given erythromycin- and florfenicol-medicated feed at a rate of 75 mg kg- 1 day- 1 and 10 mg kg- 1 day- 1 fish body weight, respectively, for 10 consecutive days. The splenic F. psychrophilum load was determined using an rpoC quantitative PCR throughout the 30-day trial. Relative to antibiotic-free controls, erythromycin treatment significantly (p < 0.05) reduced mortality of rainbow trout juveniles infected with FPG101, even when treatment was initiated after clinical signs developed.

Abstract
The pharmacokinetic profiles of florfenicol in the spotted halibut (Verasper variegatus) were investigated at 15 and 20°C water temperatures, respectively. Florfenicol content in plasma samples was analyzed using an HPLC method. Drug concentration versus time data were best fitted to a three-compartment model after a single intravenous administration (15 mg/kg BW), and fitted to a two-compartment model after an oral administration (30 mg/kg BW) at 15 and 20°C. The florfenicol concentration in the blood increased slowly during the 12 hr following an oral administration at 15°C, with a peak concentration (Cmax ) of 9.1 mg/L, and then declined gradually. The half-lives of absorption, distribution, and elimination phase were 2.18, 5.66 and 14.25 hr, respectively. The bioavailability (F) was calculated to be 24.14%. After an oral administration at 20°C, shorter half-lives of absorption (1.33 hr), distribution (2.51 hr) and elimination (9.71 hr), a higher Cmax (12.2 mg/L), and a similar F (23.98%) were found. Based on the pharmacokinetics and pharmacodynamics, an oral dose of 30 mg/kg BW was suggested to be efficacious for bacterial disease control in spotted halibut farming.

Abstract
Fish and aquatic invertebrates deserve evidence-based medicine. Pharmacologic information is available; most pharmacokinetic studies are derived from the aquaculture industry and extrapolated to ornamental fish. Conversely, advanced diagnostics and information regarding diseases affecting only ornamental fish and invertebrates require more peer-reviewed experimental studies; the examples of carp edema virus, sea star wasting disease, seahorse nutrition, and gas bubble disease of fish under human care are discussed. Antinociception is also a controversial topic of growing interest in aquatic animal medicine. This article summarizes information regarding new topics of interest in companion fish and invertebrates and highlights some future avenues for research.

Abstract
The gliding aquatic bacterium Flavobacterium columnare causes columnaris disease, a common problem for wild and farmed freshwater fish worldwide. Recently, a broth microdilution method was standardized to test the susceptibility of F. columnare against antimicrobials commonly used in aquaculture. We used this new method to measure the minimal inhibitory concentrations (MICs) of ten antimicrobials against 120 F. columnare isolates. The resulting MIC frequency distributions for each antimicrobial (1 MIC/isolate) were used to estimate epidemiological cut-off values (ECVs) which separate isolates with typical wild-type (WT) susceptibility from isolates with decreased non-wild-type (NWT) susceptibility. We identified 22 NWT isolates with elevated MICs relative to the ECV that covered 99.9% of the MIC distribution against one or more of the antimicrobials: ampicillin, enrofloxacin, erythromycin, florfenicol, flumequine, oxolinic acid or oxytetracycline. Ten of the NWT isolates had decreased susceptibility to a single antimicrobial class, six isolates to two antimicrobial classes and six isolates to three or more antimicrobial classes. The MIC frequency distributions and provisional cut-off values provide data needed to set epidemiological cut-off values to monitor for the development of antimicrobial resistance among F. columnare.
