Potent Proteasome Inhibitors Derived from the Unnatural cis-Cyclopropane Isomer of Belactosin A: Synthesis, Biological Activity, and Mode of Action was written by Kawamura, Shuhei;Unno, Yuka;List, Anja;Mizuno, Akirai;Tanaka, Motohiro;Sasaki, Takuma;Arisawa, Mitsuhiro;Asai, Akira;Groll, Michael;Shuto, Satoshi. And the article was included in Journal of Medicinal Chemistry in 2013.HPLC of Formula: 7432-21-5 This article mentions the following:

The natural product belactosin A (1) with a trans-cyclopropane structure is a useful prototype compound for developing potent proteasome (core particle, CP) inhibitors. To date, 1 and its analogs are the only CP ligands that bind to both the nonprimed S1 pocket as well as the primed substrate binding channel; however, these mols. harbor a high IC₅₀ value of more than 1 渭M. We have performed structure-activity relationship studies, thereby elucidating unnatural cis-cyclopropane derivatives of 1 that exhibit high potency to primarily block the chymotrypsin-like active site of the human constitutive (cCP) and immunoproteasome (iCP). The most active compound 3e reversibly inhibits cCP and iCP similarly with an IC₅₀ of 5.7 nM. X-ray crystallog. anal. of the yeast proteasome in complex with 3e revealed that the ligand is accommodated predominantly into the primed substrate binding channel and covalently binds to the active site threonine residue via its 尾-lactone ring-opening. In the experiment, the researchers used many compounds, for example, (S)-2-(((Benzyloxy)carbonyl)amino)-3-(1H-indol-3-yl)propanoic acid (cas: 7432-21-5HPLC of Formula: 7432-21-5).

(S)-2-(((Benzyloxy)carbonyl)amino)-3-(1H-indol-3-yl)propanoic acid (cas: 7432-21-5) belongs to indole derivatives. The indole subunit is an almost ubiquitous component of biologically active natural products, and its study has been the focus of research for decades. More than 200 indole derivatives have already been marketed as drugs or are under advanced stages of clinical trials.HPLC of Formula: 7432-21-5

Enantioseparation of derivatives of amino acids on silica modified by macrocyclic antibiotic eremomycin was written by Fedorova, I. A.;Shapovalova, E. N.;Staroverov, S. M.;Shpigun, O. A.. And the article was included in Sorbtsionnye i Khromatograficheskie Protsessy in 2015.HPLC of Formula: 7432-21-5 This article mentions the following:

Macrocyclic antibiotic eremomycin is using as chiral selector in chiral HPLC. Sorbents with this antibiotic permit to enantiosep. optical isomers of amino acids and their derivatives The main purpose of this paper was the investigation of enantioseparation of benzyloxycarbonyl (Cbz), tert-butyloxycarbonyl (Boc) derivatives of amino acids on sorbent with eremomycin. Retention time and efficiency of enantioseparation depend on structure of amino acid and radical of derivatives Retentions time of derivatives of amino acids on eremomycin increase in the row Boc < benzoyl < Cbz. More complicated structure, the presence of aromatic rings improve the enantioseparation Comparison of the results on vancomycin-sorbent shows the most successful enantioseparation on the eremomycin. In the experiment, the researchers used many compounds, for example, (S)-2-(((Benzyloxy)carbonyl)amino)-3-(1H-indol-3-yl)propanoic acid (cas: 7432-21-5HPLC of Formula: 7432-21-5).
