The effects of ketotifen fumarate (KF) and clemastine fumarate (CF) on neutrophil chemiluminescent (CL) responses to zymosan particles coated with either IgG (IgGZ), C3 (C3Z), or both (IC3Z), were examined in vitro. These opsonized zymosans caused not only detectable neutrophil superoxide anion generation evaluated by an MCLA-dependent CL (MDCL) assay, with the order of light emission being IC3...

In the title mol-ecule, C(16)H(15)ClO(4)S, the chloro-thio-phene and trimeth-oxy-phenyl rings make a dihedral angle of 31.12 (5)°. The C=C double bond exhibits an E conformation. In the crystal, C-H⋯O inter-actions generate bifurcated bonds, linking the mol-ecules into chains along the b axis.

The title compound, C10H13Cl2FN2O2S2 {systematic name: N-[(di-chloro-fluoro-methyl)-sulfanyl]-N',N'-dimethyl-N-p-tolyl-sulfamide}, is a well known fungicide. The dihedral angle between the mean plane of the di-methyl-amino group and that of the benzene ring is 32.3 (3)°. One Cl atom and one F atom of the di-chloro-fluoro-methyl-thio group are disordered over two sets of sites with an occupancy ...

Metal complexes carrying a new class of singlet carbene ligands stabilized by lateral enamine moieties are accessible by oxidative insertion into readily available chloro vinamidinium salts.

Notwithstanding their key roles in therapy and as biological probes, 7% of approved drugs are purported to have no known primary target, and up to 18% lack a well-defined mechanism of action. Using a chemoinformatics approach, we sought to "de-orphanize" drugs that lack primary targets. Surprisingly, targets could be easily predicted for many: Whereas these targets were not known to us nor to t...

The reactivity of the 2-aryl-4-chloro-6-iodoquinazolines towards palladium catalyzed sequential (Sonogashira/Suzuki-Miyaura) and one-pot two-step cross-coupling (bis-Sonogashira, and successive Sonogashira/Stille) reactions to afford novel unsymmetrical polycarbo-substituted quinazolines has been evaluated. In contrast to the chloro-bromo substituted quinazolines in which selectivity has been p...

Systemic thrombolysis with the recombinant tissue plasminogen activator (rtPA) is an effective therapy option in the treatment of acute ischaemic stroke [1]. A rare but potentially fatal side effect is the development of an orolingual angioedema [2]. Because of improvements in acute stroke therapy and an aging population the incidence of recurrent strokes is increasing and results in more patie...
