Check Digit Verification of cas no

The CAS Registry Mumber 17355-19-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,3,5 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 17355-19:
(7*1)+(6*7)+(5*3)+(4*5)+(3*5)+(2*1)+(1*9)=110
110 % 10 = 0
So 17355-19-0 is a valid CAS Registry Number.

Anti-trypanosomal activity of non-peptidic nitrile-based cysteine protease inhibitors

Burtoloso, Antonio C. B.,de Albuquerque, Sérgio,Furber, Mark,Gomes, Juliana C.,Gon?alez, Cristiana,Kenny, Peter W.,Leit?o, Andrei,Montanari, Carlos A.,Quilles, José Carlos,Ribeiro, Jean F. R.,Rocha, Josmar R.

, (2017)

The cysteine protease cruzipain is considered to be a validated target for therapeutic intervention in the treatment of Chagas disease. Anti-trypanosomal activity against the CL Brener strain of T. cruzi was observed in the 0.1 μM to 1 μM range for three nitrile-based cysteine protease inhibitors based on two scaffolds known to be associated with cathepsin K inhibition. The two compounds showing the greatest potency against the trypanosome were characterized by EC50values (0.12 μM and 0.25 μM) that were an order of magnitude lower than the corresponding Kivalues measured against cruzain, a recombinant form of cruzipain, in an enzyme inhibition assay. This implies that the anti-trypanosomal activity of these two compounds may not be explained only by the inhibition of the cruzain enzyme, thereby triggering a putative polypharmacological profile towards cysteine proteases.

Rapid Syntheses of (?)-FR901483 and (+)-TAN1251C Enabled by Complexity-Generating Photocatalytic Olefin Hydroaminoalkylation

Reich, Dominik,Trowbridge, Aaron,Gaunt, Matthew J.

supporting information, p. 2256 - 2261 (2020/01/24)

We report a common strategy to facilitate the syntheses of the polycyclic alkaloids (?)-FR901483 (1) and (+)-TAN1251C (2). A divergent synthetic strategy provides access to both natural products through a pivotal spirolactam intermediate (3), which can be accessed on a gram-scale. A photocatalytic olefin hydroaminoalkylation brings together three readily available building blocks and forges the majority of the carbon framework present in 1 and 2 in a single operation, leading to concise total syntheses. The complexity-generating photocatalytic process also provides direct access to novel non-racemic spirolactam scaffolds that are likely to be of interest to early-stage drug discovery programs.

Synthesis, bioactivity, docking and molecular dynamics studies of furan-based peptides as 20s proteasome inhibitors

Sun, Qi,Xu, Bo,Niu, Yan,Xu, Fengrong,Liang, Lei,Wang, Chao,Yu, Jiapei,Yan, Gang,Wang, Wei,Jin, Hongwei,Xu, Ping

, p. 498 - 510 (2015/03/18)

Proteasome inhibitors are promising compounds for a number of therapies, including cardiovascular and eye diseases, diabetes, and cancers. We previously reported a series of furanbased peptidic inhibitors with moderate potencies against the proteasome b5 subunit, hypothesizing that the C-terminal furyl ketone motif could form a covalent bond with the catalytic residue, threonine 1. In this context, we describe further optimizations of the furan-based peptides, and a series of dipeptidic and tripeptidic inhibitors were designed and synthesized, aiming at improved potency and better solubility. Most of the tripeptidic inhibitors demonstrated improved potency and selectivity as b5 subunit inhibitors in both enzymatic and cellular assays, and good antineoplastic activities in various tumor cell lines were also observed. However, no inhibitory effects were observed for the dipeptidic compounds, which led us to presume that a noncovalent binding mode is adopted. Docking studies and molecular dynamics simulations were carried out to verify this presumption, with results showing that the distance between the furyl ketone motif and Thr1 is slightly too long to form covalent bond.

Synthesis and biological activity of new potential agonists for the human adenosine A2A receptor

Bosch, M. Pilar,Campos, Francisco,Niubó, Itziar,Rosell, Gloria,Díaz, J. Luis,Brea,Loza, M. Isabel,Guerrero, Angel

, p. 4041 - 4053 (2007/10/03)

New adenosine derivatives have been synthesized and tested as putative agonists of adenosine receptors. Compounds 2-6 derive from the introduction of several types of substituents (electron donating, electron withdrawing, and halogens) in the para-position of the phenyl ring of the parent compound 1, and compound 7 lacks the hydroxyl group of amino alcohol 1. In radioligand binding assays using recombinant human A1, A2A, A2B, and A3 receptors, all compounds showed very low or negligible affinity for A1 and A2B receptors but compounds 3, 5, and 7 displayed a remarkably potent affinity for the A2A receptor with Ki values of 1-5 nM. Bromo derivative 3 displayed a selectivity A1/A2A = 62 and A3/A2A = 16 whereas the presence of a hydroxyl group (compound 5) improved the selectivity of A 1/A2A and A3/A2A to 120- and 28-fold, respectively. When the methoxy derivative 4 lacks the hydroxyl group on the side chain (compound 7), the binding affinity for A2A is increased to 1 nM, improving selectivity ratios to 356- and 100-fold against A1 and A3, respectively. In Chinese hamster ovary cells transfected with human A2A and A2B receptors, most compounds showed a remarkable activity for the A2A receptor, except chloro derivative 2, with EC50 values ranging from 1.4 to 8.8 nM. The compounds behaved as good A2A agonists, and all were more selective than 5′-(N-ethylcarboxamino)adenosine (NECA), with A2B/A 2A ratios of cAMP accumulation ranging from 48 for compound 2 to 666 for compound 7 while the corresponding A2B/A2A ratio for NECA was only 9. Compounds 1, 3, 5, and 7 also displayed higher selectivities than NECA up to 100-fold in isolated aortas of rat and guinea pig. In guinea pig tracheal rings precontracted by carbachol, compounds 2 and 4 were more potent than adenosine (100-fold) and NECA (10-fold), whereas compounds I and 7 displayed similar effects to NECA. Pretreatment of the tracheal rings with A2, A2A, and A2B receptor antagonists 3,7-dimethyl-L-propargylxanthine, 8-(3-chlorostyryl)caffeine, and alloxazine produced a marked inhibition of the tracheal relaxations induced by compounds 1, 2, and 4, but none of the compounds showed selectivity toward any of the adenosine receptors.
