A simple method is reported for the preparation of gram quantities of phenothiazine sulfoxides by aqueous nitrous acid oxidation of phenothiazines at room temperature. The chiral levomepromazine gave rise to diastereoisomeric products analogous to those reported for thioridazine sulfoxidation.

A variety of substituted phenothiazine cation radicals, including those from pharmacologically active derivatives, e.g. chlorpromazine, alimemazine and laevomepromazine, have been studied by means of ENDOR and TRIPLE resonance spectroscopy. These techniques allowed accurate determinations of hyperfine coupling constants, including their signs. Conclusions concerning molecular structure (e.g. twist

The solid inlet mass spectra of the N-oxide and N-oxide sulphoxide metabolites of promazine, chlorpromazine and methotrimeprazine have been determined at different temperatures and compared with the mass spectra of the main thermolytic product of the N-oxides and N-oxide sulphoxides obtained during combined gas chromatography-mass spectrometry. Diagnostic ions were produced by direct insertion of the

The invention provides methods and compositions useful for modulating signaling through Toll-like receptors. The methods involve contacting a TLR-expressing cell with a small molecule having a core structure including at least two rings. Certain of the compounds are 4-primary amino quinolines. Many of the compounds and methods are useful specifically for inhibiting immune stimulation involving at least one of TLR9, TLR8, TLR7, and TLR3. The methods may have use in the treatment of autoimmunity, inflammation, allergy, asthma, graft rejection, graft versus host disease, infection, sepsis, cancer, and immunodeficiency.

well‐known adverse effects of most promazine drugs, including levomepromazine (LPZ, Levoprome® or Nozinan®). This drug is indicated in psychiatry primarily for the treatment of schizophrenia and other schizoaffective disorders. Levomepromazine's particular sedative properties make it especially fit for use in psychiatric intensive care. Nevertheless, it is photolabile under UV‐A and UV‐B light in aerobic conditions
