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.
Pyrithione is the common name of an organosulfur compound with molecular formula C 5 H 5 NOS, chosen as an abbreviation of pyridinethione, and found in the Persian shallot. [4] It exists as a pair of tautomers, the major form being the thione 1-hydroxy-2(1H)-pyridinethione and the minor form being the thiol 2-mercaptopyridine N-oxide; it crystallises in the thione form.

A forest plot, also known as a blobbogram, is a graphical display of estimated results from a number of scientific studies addressing the same question, along with the overall results. [1] It was developed for use in medical research as a means of graphically representing a meta-analysis of the results of randomized controlled trials.
A Phase IV trial is also known as a postmarketing surveillance trial or drug monitoring trial to assure long-term safety and effectiveness of the drug, vaccine, device or diagnostic test. [1] Phase IV trials involve the safety surveillance ( pharmacovigilance ) and ongoing technical support of a drug after it receives regulatory approval to be ...
Clinical trials are medical research studies conducted on human subjects. [1] The human subjects are assigned to one or more interventions, and the investigators evaluate the effects of those interventions. [1] [2] The progress and results of clinical trials are analyzed statistically. [3] [4]

Shares of Lilly rose 4.4% to $962.02 in early trading, adding to an over 60% rise in stock value this year. In a trial involving 1,032 adults, patients who were on weekly injections showed a 94% ...
Brorphine is a piperidine-based opioid analgesic compound. [1] [2] Brorphine was originally discovered in a 2018 paper investigating functionally biased opioid compounds, with the intention of finding safer analgesics that produce less respiratory depression than typical opioids. [3]
