NOVEL INHIBITORS OF BETA-LACTAMASE

This invention provides novel β-lactamase inhibitors of the aryl- and heteroarylsulfonamidomethylphosphonate monoester class having nitrogen-based cations or quarternary ammonium groups. The compounds inhibit three classes of β-lactamases and synergize the antibacterial effects of β-lactam antibiotics (e.g., imipenem and ceftazidime) against those micro-organisms normally resistant to the β-lactam antibiotics as a result of the presence of the β-lactamases. Formula (I) or pharmaceutically acceptable salt thereof.

Study of the extraction of strontium(II) and lead(II) by crown and dithiacrown ethers

A study was carried out on the extraction of strontium(II) and lead(II) picrates by chloroform solutions of crown and dithiacrown ethers. The benzene ring substituents in benzodithia-18-crown-6 only slightly affect the extraction of strontium and lead cat

Fluorogenic and chromogenic three-dimensional ionophores as selective reagents for detecting ions in biological fluids

Novel fluorogenic and chromogenic three-dimensional ionophores are provided which selectively bond ions such as potassium, sodium, and lithium, even in neutral aqueous or alcohol media. The novel ionophores comprse an "ion-recognizing system" fused to a "
