Chemical Properties
Cyrstalline Solid
Uses
An irreversible, non-selective inhibitor of COX-1 and COX-2.
Biological Activity
o-acetyl salicylhydroxamic acid (o-asha) is an irreversible, non-selective inhibitor of cox-1 and cox-2 [1].cyclooxygenase (cox) is the key enzyme required for the conversion of arachidonic acid to prostaglandins. cyclooxygenase enzymes have been involved in diverse physiological situations and disease processes ranging from inflammation to cancer. until now, two cyclooxygenase isoforms have been identified, cox-1 and cox-2. the cox-1 enzyme is produced constitutively (i.e., gastric mucosa) and cox-2 is inducible (i.e., sites of inflammation) [2].o-acetyl salicylhydroxamic acid (o-asha) inhibited the activity of ovine cox-1 in a time-dependent and irreversible manner with a 50% b/b0 value of approximately 4.5 mm [1]. o-acetyl salicylhydroxamic acid was a novel acetylating agent. o-acetyl salicylhydroxamic acid inhibited pge2 synthesis in vivo and blocked the cyclooxygenase activity of pghs in vitro. o-acetyl salicylhydroxamic acid elicited its effects via acetylation of ser-529 in the cyclooxygenase active site [1].

Check Digit Verification of cas no
The CAS Registry Mumber 199854-00-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,8,5 and 4 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 199854-00:
(8*1)+(7*9)+(6*9)+(5*8)+(4*5)+(3*4)+(2*0)+(1*0)=197
197 % 10 = 7
So 199854-00-7 is a valid CAS Registry Number.

Synthesis, characterization, and biological properties of oxidovanadium(IV) complexes of acetylsalicylhydroxamic acid (N-acetyloxy-2-hydroxybenzamide) as potential antimicrobials
Priya, Bhanu,Kumar, Abhishek,Sharma, Neeraj
, p. 460 - 470 (2020)
New oxidovanadium(IV) complexes of composition [VO(AcSHA)2] 1 and [VO(acac)(AcSHA)] 2 are synthesized by reactions of VOSO4.5H2O and [VO(acac)2] with acetylsalicylhydroxamic acid AcSH2A (C6H4(OH)(CONHOCOCH3)) in a 1:2 molar ratio in absolute ethanol. The compounds are characterized by the Fourier-transform infrared spectroscopy, ultraviolet–visible spectroscopy, electron spin resonance, and mass spectrometry along with elemental analyses, molar conductivity, and magnetic moment measurements. The infrared spectra of the complexes suggest bonding through carbonyl and phenolic oxygen atoms (O,O coordination). The magnetic moment, electron spin resonance, and mass spectra of the complexes indicate that both exist as monomers, and a distorted square pyramidal geometry around vanadium is proposed. The thermal behavior of the complexes is studied by thermogravimetry and differential thermal analysis techniques under an N2 atmosphere, yielding VO2 as the decomposition product. The in vitro antimicrobial assays against pathogenic Gram-positive bacteria, Gram-negative bacteria, and fungi (minimum inhibitory concentration method) show the appreciable antimicrobial potential relative to the respective standard drugs, tetracycline hydrochloride, and fluconazole.
α-effect of hydroxamate ions in micellar mediated reactions of p-nitrophenyl acetate

The rate-surfactant concentration profiles for the reaction of p-nitrophenyl acetate (PNPA) with three hydroxamate ions (R C6H 4CO NHO-; R = H, 2-OH, 4-OCH3) in aqueous solutions of cetyltrimethylammonium bromide (CTAB) have been studied at 27°C (pH 7.7). In transferring the reaction from water to micelles of CTAB, an increase in reaction rates have been observed.
