[Translation] A single-center, randomized, open-label, single-dose, two-formulation, two-period, two-sequence crossover design to compare the pharmacokinetics of potassium citrate bismuth capsules in fasting subjects
The aim was to study the pharmacokinetic characteristics of a single fasting oral administration of bismuth potassium citrate capsules (120 mg (calculated as Bi2O3)) developed and produced by Chongqing Kerui Pharmaceutical (Group) Co., Ltd. to healthy subjects; using bismuth potassium citrate tablets (Gastrodenol®, 120 mg (calculated as Bi2O3)) certified by TORA LABORATORIES.S.L. as the reference preparation, to prove that the human body absorption of bismuth of the test preparation is not higher than that of the reference preparation.

Photoinduced Radical Desulfurative C(sp3)–C(sp2) Coupling via Electron Donor–Acceptor Complexes
Herein, we disclose a radical desulfurative C-C coupling protocol for the synthesis of 4-alkylpyridines. A variety of substituents on both benzyl thiols and 4-cyanopyridines are tolerated. The reaction is carried out under mild and photocatalyst- and transition-metal-free conditions. Preliminary mechanistic studies show that an electron donor-acceptor complex is formed between benzyl thiols and 4-cyanopyridines under alkaline conditions. Then, a variety of 1°, 2°, and 3° C(sp3)-centered radicals was formed by cleavage of the C-S bond, and the 4-alkylpyridines were achieved through a radical-radical coupling with the pyridyl radical anion.
