The synthesis, in vitro/in vivo antifungal evaluation and a structure-activity relationship (SAR) study of 3(2H)-pyridazinones was carried out. The results reported here may be helpful in the structural identification and understanding of the minimum structural requirements for these molecules acting as antifungal agents. In addition, the most active structure in this series was tested for its capacity of inhibiting Saccharomyces cerevisiae beta1,3-glucan synthase and chitin synthase, enzymes that catalyze the synthesis of the major polymers of the fungal cell wall.

932-22-9, Name is 4,5-Dichloro-3(2H)-pyridazinone, belongs to pyridazine compound, is a common compound. Product Details of 932-22-9In an article, once mentioned the new application about 932-22-9.

4-Cyano-3-oxido-1-beta-D-ribofuranosylpyridazinium (10a) has been prepared from 4-cyano-3(2H)-pyridazinone by using a low-temperature, kinetically controlled, silyl Hilbert-Johnson reaction followed by deblocking of the resulting triacetate derivative with NaHCO3 in methanol. 10a is apparently the first example of a mesoionic analogue of a pyrimidine nucleoside. It was discovered as a urine metabolite of 4-cyano-3(2H)-pyridazinone in mice. 10a possesses Gram-negative antibacterial activity in vivo against a systemic Escherichia coli infection in mice with an ED50 of 25-50 mg/kg. A series of 4-substituted 3-oxidooxyridazinium ribonucleosides, 11a-h, were synthesized as analogues of 10a. 4-Chloro-3-oxido-1-beta-D-ribofuranosylpyridazinium (11a) was found to be several times more active than 10a against E. coli in vitro although it showed no in vivo activity.
