After being ingested by a dog, afoxolaner is distributed throughout the dog’s body. When fleas or ticks bite the dog, they are exposed to the drug and killed during their blood meal. Mechanism of action Afoxolaner (the active ingredient of NEXGARD) and other isoxazolines with insecticidal and tickicidal efficacy are non-competitive GABA (gamma-aminobutyric acid) receptor antagonists, much more selective for GABA receptors in insects or ticks, than for those in mammals, including humans. They bind to chloride channels in nerve and muscle cells, which blocks the transmission of neuronal signals. Affected parasites are paralyzed and die.This mechanism exists not only in insects but also in mammals and other vertebrates. However the binding affinity of afoxolaner to GABA receptors of invertebrates is much higher than to GABA receptors in vertebrates. For this reason it is significantly less toxic to mammals than to insects and other pests. Metabolism Afoxolaner is an isoxazoline compound. It works by blocking the transmissions of neuronal signals in insects. They do this by binding to chloride channels in nerve and muscle cells, causing the receptors to stop working. This in turn paralyses the parasites and kills them.Afoxolaner toxicity to fleas ensures that they die within 24 hours of it being administered. But the dog is unaffected, due to the specific selective nature of the drug. Pharmacokinetics Afoxolaner orally administered to dogs was rapidly absorbed into blood. Max. blood levels were reached 2 to 12 hours after administration. Mean half-life in blood ranged from 7.7 to 17.8 days. Bioavailability was estimated to be approx. 74%. Half-life was higher in Collies than in Beagles, but no serious adverse effects were observed after treatment of Collies at 25 mg/kg bw (i.e. ~10x the therapeutic dose).Absorbed afoxolaner binds strongly (>99%) to blood proteins but it seems not to cause displacement of other drugs with high protein binding capacities.In dogs afoxolaner is slowly broken down into various metabolites, the major ones being a hydroxylate and a glucuronide. Elimination of both the metabolites and the parent compound occurrs mainly via biliary excretion and to a lesser extent through urine. Uses Afoxolaner (brand name NexGard®) is used to treat and control flea and tick infestations in dogs. After being ingested by a dog, afoxolaner is distributed throughout the dog's body. When fleas or ticks bite the dog, they are exposed to the drug and killed during their blood meal. Enzyme inhibitor This orally active isoxazoline-based pesticide (FW = 901.18 g/mol; CAS 1093861-60-9; IUPAC Name: 4-[5-[3-chloro-5-(trifluoromethyl)phenyl]- 4,5-dihydro-5-(trifluoromethyl)-3-isoxazolyl]-N-[2-oxo-2-[(2,2,2-trifluoroethyl) amino]ethyl]-1-naphthalenecarboxamide, is highly active against fleas (Ctenocephalides felis) and ticks (Dermacentor variabilis) in dogs. Afoxolaner is more potent, when tested in vitro, than any other compound ever tested in the membrane feeding system, including the avermectins. At an oral dose of 2.5 mg/kg, afoxolaner reaches pharmacologically effective plasma concentrations (0.1–0.2 μg/mL), blocking native and expressed insect GABA-gated chloride channels with nanomolar potency. Afoxolaner has comparable potency between wild-type channels as well as channelspossessing the dieldrin resistance-conferring Alanine-302-Serine mutation. Lack of cyclodiene cross-resistance for afoxolaner suggests that afoxolaner blocks GABA-gated chloride channels by binding at a site topologically distinct from the cyclodienes.   afoxolaner Preparation Products And Raw materials Raw materials 4-{3-[3-chloro-5-(trifluoromethyl)phenyl]-4,4,4-trifluorobut-2-enoyl}-N-{2-oxo-2-[(2,2,2-trifluoroethyl)amino]ethyl}-1-naphthamide

                                      Group profiles

Leader Biochemical Group is a large leader incorporated industry manufacturers and suppliers of advanced refined raw materials From the year of 1996 when our factory was put into production to year of 2020, our group has successively invested in more than 52 factories with shares and subordinates.We focus on manufacture Pharm & chemicals, functional active ingredients, nutritional Ingredients, health care products, cosmetics, pharmaceutical and refined feed, oil, natural plant ingredients industries to provide top quality of GMP standards products.All the invested factories' product lines cover API and intermediates, vitamins, amino acids, plant extracts, daily chemical products, cosmetics raw materials, nutrition and health care products, food additives, feed additives, essential oil products, fine chemical products and agricultural chemical raw materials And flavors and fragrances. Especially in the field of vitamins, amino acids, pharmaceutical raw materials and cosmetic raw materials, we have more than 20 years of production and sales experience. All products meet the requirements of high international export standards and have been recognized by customers all over the world. Our manufacture basement & R&D center located in National Aerospace Economic & Technical Development Zone Xi`an Shaanxi China. Now not only relying on self-cultivation and development as well as maintains good cooperative relations with many famous research institutes and universities in China. Now, we have closely cooperation with Shanghai Institute of Organic Chemistry of Chinese Academy of Science, Beijing Institute of Material Medical of Chinese Academy of Medical Science, China Pharmaceutical University, Zhejiang University. Closely cooperation with them not only integrating Science and technology resources, but also increasing the R&D speed and improving our R&D power. Offering Powerful Tech supporting Platform for group development. Keep serve the manufacture and the market as the R&D central task, focus on the technical research.  Now there are 3 technology R & D platforms including biological extract, microorganism fermentation and chemical synthesis, and can independently research and develop kinds of difficult APIs and pharmaceutical intermediates. With the strong support of China State Institute of Pharmaceutical Industry (hereinafter short for CSIPI), earlier known as Shanghai Institute of Pharmaceutical Industry (SIPI), we have unique advantages in the R & D and industrialization of high-grade, precision and advanced products.  Now our Group technical force is abundant, existing staff more that 1000 people, senior professional and technical staff accounted for more than 50% of the total number of employees, including 15 PhD research and development personnel, 5 master′ S degree in technical and management personnel 9 people. We have advanced equipment like fermentation equipment and technology also extraction, isolation, purification, synthesis with rich production experience and strict quality control system, According to the GMP required, quickly transforming the R&D results to industrial production in time, it is our advantages and our products are exported to North and South America, Europe, Middle East, Africa, and other five continents and scale the forefront in the nation, won good international reputation.  We believe only good quality can bring good cooperation, quality is our key spirit during our production, we are warmly welcome clients and partner from all over the world contact us for everlasting cooperation, Leader will be your strong, sincere and reliable partner in China.
