Ammine(2-ethylpyridine-κN)bis(tri-tert-butoxysilanethiolato-κS)cobalt(II)

Acta Crystallographica Section E Structure Reports Online, 2007
The title compound, [Co(C12H27O3SSi)2(C7H9N)(NH3)], was obtained by the reaction of dimeric [Co{SSi(OtBu)3}2(NH3)]2 with 2-ethyl­pyridine. The CoII atom is coordinated by two S atoms from two silanethiol­ate ligands and two N atoms, one from ammonia and one from a 2-ethyl­pyridine mol­ecule.

Disrupting Substance Use Disorder: The Chemistry of Iboga Alkaloids

European Journal of Organic Chemistry, Volume 27, Issue 36, September 23, 2024.
The iboga alkaloid class of monoterpene indole alkaloids have long inspired synthetic chemists in their structural complexity and dense functionalization. Their unique anti‐addictive properties have propelled this class of natural products into potential lead compounds for drug discovery efforts as well.

Reactivity of 2-nitroxysuccinate 3-hydroxy-6-methyl-2-ethylpyridine and reference drugs in model NO-generating systems

Доклады Академии наук, 2019
The ability of the 2-nitroxysuccinate 3-hydroxy-6-methyl-2-ethylpyridine (I) compound to generate nitrite ions (NO2) and nitrogen monoxide (NO) in model systems with cysteine (Cys) and deoxyhemoglobin (Hb) has been studied. It has been established that there is a more efficient release NO2 and NO from compound I than from Nicorandil.
