Description
Sinefungin is a nucleoside S-adenosyl-1-methionine analog that functions as a potent, competitive inhibitor of methyltransferases, including protein, DNA, and RNA methyltransferases. It exhibits a high affinity for adenine-specific DNA methyltransferase M.TaqI and has been shown to inhibit biofilm formation by Streptococcus pneumoniae.
Uses
Used in Biochemical Research:
Sinefungin is utilized as a bioprobe to block methyltransferase-dependent pathways, providing valuable insights into the role of these enzymes in various biological processes.
Used in Antimicrobial Applications:
Sinefungin is used as an antifungal agent with broad biological activity, isolated from Streptomyces species. It inhibits the methylation of bases in DNA and RNA, which in turn alters cytosine deamination and gene expression, contributing to its antimicrobial properties.
Used in Drug Development:
Sinefungin's derivatives can be employed as inhibitors and structure probes for human protein lysine methyltransferase SETD2, aiding in the development of new therapeutic agents targeting this enzyme.
Used in Microbiology:
Sinefungin is used to inhibit biofilm growth in Streptococcus pneumoniae, offering potential applications in controlling bacterial infections and understanding the mechanisms of biofilm formation.
Biochem/physiol Actions
Probable transcription factor. Plays a critical role in the control of immune response.

Check Digit Verification of cas no
The CAS Registry Mumber 58944-73-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,9,4 and 4 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 58944-73:
(7*5)+(6*8)+(5*9)+(4*4)+(3*4)+(2*7)+(1*3)=173
173 % 10 = 3
So 58944-73-3 is a valid CAS Registry Number.

Synthesis of Sinefungin and Its C-6' Epimer
Geze, M.,Blanchard, P.,Fourrey, J. L.,Robert-Gero, M.
, p. 7638 - 7640 (1983)
A synthesis of the nucleoside antibiotic sinefungin (1) and its C-6' epimer is described.It was accomplished by coupling a functionized adenosine derivative, 2, with an aldehyde synthon, 3, derived from L-amino acid to give the sinefungin precursor 4.The construction of the skeleton of the glycosyl moiety of sinefungin (1) could be achieved starting from methyl riboside.The adopted sequence was probed further by synthesizing the sinefungin analogue 9b (two C-6' epimers).This synthesis established that the Hoffmann rearrangement of both amides 8b took place with complete retention of configuration at C-6'.Finally, sinefungin derivatives 9c were obtained, and one of these found to be identical with the same derivative prepared from authentic sinefungin (1).It was easily converted to sinefungin (1).

Sinefungin 1a and 6-epi-sinefungin 1b have been prepared from adenosine and L-aspartic acid.The key step in the synthesis was the coupling of the radical derived from 14 with the unsaturated amide 13.The latter was obtained by a radical reaction from L-as
