Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. 4865-84-3. Introducing a new discovery about 4865-84-3, Name is 1,2-Benzisoxazole-3-acetic Acid

Facile preparation of protected benzylic and heteroarylmethyl amines via room temperature Curtius rearrangement

A step-wise, room temperature procedure for acyl azide formation and the subsequent Curtius rearrangement of phenyl and heteroaryl acetic acids is described. We have developed a protocol for room temperature Curtius rearrangement in MeOH or CHCl3 that provides an improvement over standard conditions, avoiding the use of additives or heat. This room temperature optimization of the Curtius rearrangement prevents the formation of side products often observed with benzylic acids, allowing access to a variety of benzylic and heteroarylmethyl amines.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 4865-84-3, help many people in the next few years.4865-84-3

Hypoxia-Selective Antitumor Agents. 3. Relationships between Structure and Cytotoxicity against Cultured Tumor Cells for Substituted N,N-Bis(2-chloroethyl)anilines

A series of aniline mustards with a wide range of electron-donating and -withdrawing substituents in the 3- and 4-positions has been synthesized and evaluated for cytotoxicity in cell culture to examine the potential of using nitro group deactivated nitrogen mustards for the design of novel hypoxia-selective anticancer drugs (Denny, W.A.; Wilson, W.R.J.Med Chem. 1986, 29, 879).Hydrolytic half-lives in tissue culture media, determined by bioassay against a cell line (UV4) defective in the repair of DNA interstrand cross-links showed the expected dependence on the Hammett electronic parameter, ?, varying from 0.13 h for the 4-amino analogue to >100 h for analogues with strongly electron-withdrawing substituents.Cytotoxic potencies in aerobic UV4 cultures showed a similar dependence on ?.This dependence predicted that the 4-nitroaniline mustard would be 7200-fold less potent than its potential six-electron reduction product, the 4-amino compound, in growth inhibition assays using a 1-h drug exposure.The measured differential was much lower (225-fold) because of the instability of the latter compound, but a differential of 17500-fold was observed in the initial rate of killing by using a clonogenic assay.The potential for formation of reactive mustards by reduction to the amine or hydroxylamine was demonstrated by the 4-nitroso compound, which had an aerobic toxicity similar to that of the amine.Although these features confirmed the original rationale, the 3-nitro- and 4-nitroaniline mustards had only minimal hypoxic selectivity against UV cells.Toxicity to hypoxic cells appears to be limited by the low reduction potentials of these compounds and consequent lack of enzymatic nitroreduction.However, this study has demonstrated that nitro groups can be used to latentiate aromatic nitrogen mustards and indicates that examples with higher reduction potentials could provide useful hypoxia-selective therapeutic agents.

Synthesis, anti-bacterial, anti-asthmatic and anti-diabetic activities of novel N-substituted-2-(benzo[d]isoxazol-3-ylmethyl)-1H-benzimidazoles

(Chemical Equation Presented) Synthesis of a series of novel class of N-substituted-2-(benzo[d]isoxazol-3-ylmethyl)-1H-benzimidazoles (4) by the condensation of o-phenylenediamine (1) with benzo[d]isoxazol-3-yl-acetic acid (2) and subsequent reactions with different types of electrophiles have been reported. Some compounds exhibited promising anti-bacterial activity against Salmonella typhimurium, however poor activity against Staphylococcus aureus. The compound 4t was found to have high activity even at 1 mug/ml compared to Cephalexin against S. aureus. The biological activity against PDE-IV for potential anti-asthmatic effect and against DP-IV and PTP-1B for potential anti-diabetic effects was disappointing.
