The enantioselective domino Heck/cross-coupling has emerged as a powerful tool in modern chemical synthesis for decades. Despite significant progress in relative rigid skeleton substrates, the implementation of asymmetric Heck/cross-coupling cascades of highly flexible haloalkene substrates remains a challenging and and long-standing goal. Here we report an efficient asymmetric domino Heck/Tsuji-Trost reaction of highly flexible vinylic halides with 1,3-dienes enabled by palladium catalysis.

Background: Rituximab pharmacokinetics in patients with membranous nephropathy (MN) exhibit significant interindividual variability. Accurate measurement of serum rituximab concentrations is essential for effective therapeutic monitoring. This study develops a highly sensitive time-resolved fluoroimmunoassay (TRFIA) for rituximab (rituximab-TRFIA) with a wide detection range, aimed at enhancing therapeutic drug monitoring in MN treatment.

Accurate measurement of serum parathyroid hormone (PTH) is crucial for diagnosing and managing endocrine and osteological diseases. Conventional immunoassay methods struggle with cross reactivity issues between full-length PTH and truncated fragments or post-translationally modified forms. Both the standardization of PTH assays and the peptide's stability are concerning.

The diagnosis of chickenpox remains a difficult task especially in cases of breakthrough chickenpox, so the development of reliable laboratory tests is necessary. The simplest and most sensitive serological test for detecting antibodies in human and animal sera is the passive hemagglutination reaction (PHAR).
