Unlike other prokinetic drugs that are utilized in the management of functional dyspepsia, acotiamide shows little/no affinity for serotonin or dopamine D-2 receptors. Acotiamide is the world’s first approved treatment for functional dyspepsia diagnosed by Rome III criteria, with its first approval occurring in Japan. Phase
III trials in this patient population are in preparation in Europe, with phase II trials EPZ-6438 mw completed in the USA and Europe. This article summarizes the milestones in the development of acotiamide, leading to its first approval for use in patients with functional dyspepsia.”
“Structure-activity relationship (SAR) studies of 2-(quinazolin-4-ylthio)thiazole derivatives, which are for optimizing the in vitro and in vivo antiacute myeloid leukemia (AML) activity of a previously identified FLT3 inhibitor 2-(6,7-dimethoxyquinazolin-4-ylthio)thiazole (1), are described. SAR studies centering around the head (thiazole) and tails (6- and 7-positions) of the quinazoline moiety of 1 led to the discovery of a series of compounds that exhibited significantly dincreased potency
against FLT3-driven AML MV4-11 cells. Preliminary in vivo assays were carried out on three highly active compounds, whose results showed that 1-5-[7-(3-morpholinopropoxy)quinazolin-4-ylthio]-[1,3,4]thiadiazol-2-yl-3-p-tolylurea (20c) had the highest in vivo activity. Further in vitro and in vivo anti-AML studies were then performed on 20c; in an MV4-11 xenograft mouse model, a once-daily dose of 20c at 100 mg/kg for 18 days led to complete tumor regression NF-��B inhibitor without obvious toxicity. Western blot and immunohistochemical analysis were carried out to illustrate the
mechanism of action of 20c.”
“Coding variants in tumor necrosis factor PR171 receptor superfamily member 13B (TNFRSF13B) have been implicated in common variable immunodeficiency (CVID), but the functional effects of such mutations in relation to the development of the disease have not been entirely established. To examine the potential contribution of TNFRSF13B variants to CVID, we have applied an evolutionary approach by sequencing its coding region in 451 individuals belonging to 26 worldwide populations, in addition to controls, patients with CVID and selective IgA deficiency (IgAD) from Italy. The low level of geographical structure for the observed genetic diversity and the several neutrality tests performed confirm the absence of recent population-specific selective pressures, suggesting that TNFRSF13B may be involved also in innate immune functions, rather than in adaptive immunity only. A slight excess of rare derived alleles was found in patients with CVID, and thus some of these variants may contribute to the disease, implying that CVID probably fits the rare variants rather than the common disease/common variant paradigm.
