• 용도

  4-AP는 탈수초성 시신경병 환자의 시력을 개선시키는 데 유용하다.

• 개요

  4-Aminopyridine (4-AP, fampridine, dalfampridine) is the first drug approved by the FDA to improve walking in patients with multiple sclerosis (MS). Dalfampridine is a voltage-gated potassium channel blocker that readily penetrates the CNS and increases the conduction and duration of action potential across nerve fibers resulting in enhanced functionality as observed in the walking speed of MS patients.
  From a safety perspective, seizure was the most important adverse event from various dalfampridine clinical trials. Therefore, dalfampridine is contraindicated in patients with a history of seizures. Since dalfampridine is primarily excreted by the kidney as unchanged drug, it is also contraindicated in patients with moderate to severe renal impairment. Assessing the overall benefit–risk profile from various clinical trials, the FDA approved dalfampridine (daily oral dose of 10 mg, b.i.d.) to improve walking in MS patients with existing gait impairment.

• 화학적 성질

  4-aminopyridine is a white crystalline solid that contains about 98% active ingredient. It is soluble in water and slightly soluble in benzene and ether. 4-Aminopyridine formulations are classifi ed by the US Environmental Protection Agency (US EPA) as restricted use pesticides (RUPs) and therefore should be purchased and used only by certifi ed and trained workers and applicators. Avitrol is available as grain baits or as a powder concentrate. It is one of the most prominent avicides. It is registered with the EPA for use against red-winged blackbirds, blackbirds in agricultural fi elds, grackles, pigeons, and sparrows around public buildings, and various birds around livestock feeding pens. Avitrol repels birds by poisoning a few members of a fl ock, causing them to become hyperactive.

• 용도

  Avitrol (4-aminopyridine), has repellent–toxicant properties for birds and is classed as a severe poison and irritant. This secondary bird repellent can be used as a broadcast bait, causing uncoordinated flight and distress calls and escape responses in nearby birds.

• 정의

  ChEBI: 4-aminopyridine is an aromatic amine that is pyridine bearing a single amino substituent at position 4. An orphan drug in the US, it is used to improve walking in adults with multiple sclerosis. It has a role as an avicide, a potassium channel blocker and an orphan drug. It is an aromatic amine and an aminopyridine.

• 일반 설명

  White crystalline material with no odor. Used as an avicide, an intermediate and as a fixer for some textile dyes.

• 반응 프로필

  4-Aminopyridine neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

• 건강위험

  4-Aminopyridine, a pyridine compound, is an extremely effective bird poison. In agriculture, 4-AP is used as an extremely effective bird poison sold under the brand name Avitrol. It is highly toxic to all mammals including humans if dosages are exceeded, and as an experimental drug, the recommended dose data is unavailable.

• 화재위험

  Material may produce irritating or poisonous gases in fire. Runoff from fire control water may give off irritating or poisonous gases.

• Safety Profile

  Poison by ingestion, subcutaneous, intravenous, and intraperitoneal routes. Human systemic effects by ingestion: hallucinations and vomiting. When heated to decomposition it emits toxic fumes of NOx,.

• 잠재적 노출

  Used as a chemical intermediate in pharmaceuticals; as an agricultural chemical for field crops; and as a bird repellent and poison

• 운송 방법

  UN2671 Aminopyridines, Hazard Class: 6.1; Labels: 6.1-Poisonous materials

• Purification Methods

  Crystallise the aminopyridine from *benzene/EtOH, then recrystallise it twice from water, then crush and dry it for 4hours at 105o [Bates & Hetzer J Res Nat Bur Stand 64A 427 1960]. It has also been crystallised from EtOH, *benzene, *benzene/pet ether, toluene and sublimes in a vacuum. [Beilstein 22/9 V 106.]

• 비 호환성

  Sodium nitrite, strong oxidizers. Avoid contact with acid anhydrides, acid chlorides; and strong acids.

• 폐기물 처리

  Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposalIncineration with nitrogen oxides removal from effluent gas.
