The most common side effects include thromboembolic events (problems due to the formation of blood clots in the blood vessels), diarrhea, and hypertension (high blood pressure). [ 3 ] Vadadustat was approved for medical use in the European Union in April 2023, [ 3 ] and in the United States in March 2024.
2-Aminopyridine is an organic compound with the formula H 2 NC 5 H 4 N. It is one of three isomeric aminopyridines. It is a colourless solid that is used in the production of the drugs piroxicam, sulfapyridine, tenoxicam, and tripelennamine. It is produced by the reaction of sodium amide with pyridine, the Chichibabin reaction. [3]
2-Bromopyridine reacts with butyllithium to give 2-lithiopyridine, [2] which is a versatile reagent. [3] Pyrithione can be prepared in a two-step synthesis from 2-bromopyridine by oxidation to the N-oxide with a suitable peracid followed by substitution using either sodium dithionite or sodium sulfide with sodium hydroxide to introduce the thiol functional group.
3-Bromopyridine is an aryl bromide and isomer of bromopyridine with the formula C 5 H 4 BrN. It is a colorless liquid that is mainly used as a building block in organic synthesis. [1] [2] It participates as a substrate in many reactions associated with aryl halides, e.g., the Heck reaction [3] and Buchwald-Hartwig coupling. [4]
[2] [3] It is taken by mouth. [2] Side effects of droxidopa include headache, dizziness, nausea, and hypertension, among others. [2] Droxidopa is a synthetic amino acid precursor which acts as a prodrug to the neurotransmitter norepinephrine (noradrenaline). [4] Hence, it acts as a non-selective agonist of the α-and β-adrenergic receptors.
