The title compound, 2C(17)H(20)N(2)O·CH(2)Cl(2), was obtained by N-oxidation of the parent formamidine with m-chloro-peroxy-benzoic acid (m-CPBA). This is the first use of the above-mentioned synthetic route for the preparation of hydroxy-amidines. The title compound crystallizes as a cyclic dimer resulting from the presence of O-H⋯O and N-H⋯N hydrogen bonds.

Compounds containing pyrazolopyrimidine scaffolds were designed and synthesized as toll-like receptor 7 (TLR7) agonists. Thirty-three compounds, including 22 novel compounds, were prepared, and their structures were identified using nuclear magnetic resonance spectroscopy and mass spectrometry. TLR7 agonist activity was determined in HEK-Blue hTLR7 reporter cells.

Acetylcholinesterase (AChE) is a pivotal enzyme in nerve conduction, controlling its activity with its inhibitor (AChEI) is crucial for the treatment of Alzheimer's disease (AD). However, current AChEIs are associated with considerable adverse effects. Previous work has identified 2α,3β,19α,23-tetrahydroxy-12-ene-28-oic acid (RLMS) as a promising natural AChEI.

Bile acids (BAs) are essential signaling molecules that engage in host and gut microbial metabolism, playing a crucial role in maintaining organismal stability. Liquid chromatography-mass spectrometry (LC-MS) is a widely employed technique for metabolite analysis in biological samples due to its high sensitivity, excellent specificity, and low detection limits. This method has emerged as the mainstream approach for the detection and analysis of BAs.

In a systematic study, six pseudopolymorphic coordination polymers containing the ditopic 1,3-di(pyridin-4-yl)urea ligand (4bpu) constructed with d metal cations, possessing the formula {[M(4bpu)I]S} [(M = Zn, Cd and Hg), (S = MeOH or EtOH)], namely Zn-MeOH, Zn-EtOH, Cd-MeOH, Cd-EtOH, Hg- and Hg-EtOH were obtained. The title compounds were characterized by single-crystal X-ray diffraction analysis (SC-XRD), elemental analysis (CHN), FT-IR spectroscopy, thermogravimetric analysis (TGA), and powder X-ray diffraction (PXRD). The diffraction studies show that these compounds are isostructural 1D zig-zag chain coordination polymers which is also confirmed using XPac 2.
