7438-77-9

Orn-δ-NOH, also known as δ-ornithine hydroxamate, is a chemical compound derived from the amino acid ornithine. It is characterized by the presence of a hydroxamate group (-CO-NH-OH) attached to the δ-carbon of the ornithine molecule. This modification enhances its ability to chelate metal ions, particularly iron, which is crucial for its biological activity. Orn-δ-NOH is of interest in the field of medicine and biochemistry due to its potential applications in targeting and inhibiting certain enzymes, such as those involved in iron metabolism. Its ability to bind iron makes it a candidate for the development of therapeutic agents against diseases where iron dysregulation plays a role, such as certain types of anemia or neurodegenerative disorders.

Check Digit Verification of cas no

The CAS Registry Mumber 7438-77-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,3 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7438-77:
(6*7)+(5*4)+(4*3)+(3*8)+(2*7)+(1*7)=119
119 % 10 = 9
So 7438-77-9 is a valid CAS Registry Number.

New Pyoverdin-Type Siderophores from Pseudomonas fluorescens

Mohn, G.,Taraz, K.,Budzikiewicz, H.

, p. 1437 - 1450 (2007/10/02)

The structures of two new pyoverdins (GM-I and GM-II) isolated from the culture medium of Pseudomonas fluorescens have been elucidated by spectroscopic methods and degradation studies.The pyoverdins consist of a chromophore which could be identified as (1S)-5-amino-2,3-dihydro-8,9-dihydroxy-1H-pyrimidoquinoline-1-carvoxylic acid substituted at the amino group with 3-carboxypropanoyl or a siccinamoyl residue and at the carboxy group with the N-terminus of D-Ala-D-Lys-Gly-Gly-D-threo-(OH)Asp-D-Glu-D-Ser-L-Ala-D-Ala-L-Ala-L-N5-(OH)Orn.According to the "short-hand" nomenclatur proposed in the two compounds should be characterized as pyoverdin-X-akGGd'qsAaaAO'*-SUCA and pyoverdin-Q-akGGD'qaAaaAO'*-SUC.
