The antitumor and antimitotic action of the pyridine-tritiated square-planar Pt complex cis-dichloro(dipyridine)platinum(II) (I) [15227-42-6] seems to depend on the dissociation of 1 or both chlorine atoms from the platinum atom. The resulting cationic, aquated species subsequently forms a bond with nucleic acid. I associate avidly with calf thymus DNA, high mol. weight yeast RNA, and bacterial and yeast tRNA, but not with bovine serum albumin, dextran, or purified erythrocyte membranes. Dialysis of the Pt-nucleic acid complexes in distilled water or NaCl results in loss of a portion of the original radioactivity. The Pt-DNA bond is resistant to dissociation by solubilization in alkali followed by trichloroacetic acid (TCA) precipitation Bonding of I to DNA in vitro is inhibited by NaCl; however, prior alkylation of the DNA with nitrogen mustard does not influence its subsequent bonding with I. I associate with intact Ehrlich ascites tumor cells in vitro at 2.deg. and 37.deg. and resists dissociation by washing with saline or TCA as well as solubilization in alkali followed by re-precipitation with TCA.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Trifluoromethanesulfonato-O complexes of platinum(II) and palladium(II), published in 1988, which mentions a compound: 15227-42-6, mainly applied to trifluoromethanesulfonato palladium platinum complex; hydrolysis kinetics trifluoromethanesulfonato platinum, Formula: C10H10Cl2N2Pt.

Reaction of chloroplatinum(II) and chloropalladium(II) complexes containing amine, pyridine, or phosphine ligands at or above room temperature with anhydrous CF3SO3H gave F3CSO3–O complexes, characterized spectroscopically. The complexes cis-[Pt(NH3)2(OSO2CF3)2], trans-[Pt(NH3)2Cl(OSO2CF3)], Pt(en)Cl(OSO2CF3)], [Pt(dppe)(OSO2CF3)2], [Pt(py)2Cl(OSO2CF3)], [Pt(terpy)(OSO2CF3)][CF3SO3], (terpy = 2,2′:6′,2′-terpyridine), trans-[Pd(NH3)2Cl(OSO2CF3)], [Pd(en)(OSO2CF3)2], [Pd(bpy)(OSO2CF3)2] (bpy = 2,2′-bipyridine), and [Pd(PPh3)2(OSO2CF3)2] were isolated. Aquation reactions of selected complexes showed that F3CSO3- hydrolysis is rapid for complexes of both PtII and PdII. Pt(O3SCF3)2 complexes exhibit 2 consecutive rate processes, with k1/k2 ca. 5, consistent with sequential hydrolysis of both anions. Coordinated CF3SO3- in these complexes may be substituted even by neutral coordinating O-donor solvents.

Let’s take a look at the latest research on this compound (cas:15227-42-6).

Multinuclear solid-state NMR (SSNMR) experiments were performed on cisplatin and four related square-planar compounds The wideband uniform rate smooth truncation-Carr-Purcell-Meiboom-Gill (WURST-CPMG) pulse sequence was used in NMR experiments to acquire 195Pt, 14N, and 35Cl ultra-wideline NMR spectra of high quality. Standard Hahn-echo and magic-angle spinning 195Pt NMR experiments are also performed to refine extracted chem. shielding (CS) tensor parameters. Platinum magnetic shielding (MS) tensor orientations are calculated using both plane-wave d. functional theory (DFT) and standard DFT methods. The tensor orientations are highly constrained by mol. symmetry elements, but also influenced to some degree by intermol. interactions. 14N WURST-CPMG experiments were performed on three compounds and elec. field gradient (EFG) parameters (the quadrupolar coupling constant, Cq, and the asymmetry parameter, ηq) are reported. First principles calculations of the 14N EFG tensor parameters and orientations and affirm their dependence on the local hydrogen bonding environment. 35Cl WURST-CPMG experiments on cisplatin and transplatin are reported, using two different static magnetic fields to extract EFG and CS tensor parameters, and 35Cl EFG tensor magnitudes and orientations are predicted using 1st principles calculations Transverse (T2) relaxation data for all nuclei were used to study heteronuclear dipolar relaxation mechanisms, as well as the nature of the local hydrogen bonding environments.

Recommanded Product: 15227-42-6. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: cis-Dichlorobis(pyridine)platinum(II), is researched, Molecular C10H10Cl2N2Pt, CAS is 15227-42-6, about Activation of the trans geometry in platinum antitumor complexes: a survey of the cytotoxicity of trans complexes containing planar ligands in murine L1210 and human tumor panels and studies on their mechanism of action. Author is Farrell, Nicholas; Kelland, Lloyd R.; Roberts, John D.; Van Beusichem, Marijo.

The cytotoxicity of transplatinum complexes of structural formula trans-[PtCl2(L)L’)] {L = L’ = pyridine or thiazole, or L = quinoline (R’ = methyl; R” = Me, Ph or CH2phenyl) and L’ = R’R”SO] has been studied in murine L1210 and human tumor cell lines. The results confirm previous observations that use of a sterically hindered planar ligand greatly enhances cytotoxicity, in comparison to trans-[PtCl2(NH3)2], such that in some cases cytotoxicity equivalent to that of the clin. used agent cisplatin [cis-{PtCl2(NH3)2]] is obtained. Results from both the panel of human ovarian carcinoma cell lines and the National Cancer Institute screening panel confirm a different pattern of cytotoxicity, with respect to cisplatin. The new trans-platinum complexes are also non-cross-resistant with cisplatin in both murine and human (human ovarian carcinoma panel) tumor cell lines. Preliminary mechanistic studies using both cis- and trans-[PtCl2(pyridine)2] in L1210 cells have been carried out, to delineate the reasons for both the dramatically enhanced cytotoxicity and the lack of cross-resistance with the clin. used agents. Intracellular uptake is enhanced for pyridine relative to ammine (NH3) complexes. The pyridine complexes also inhibit DNA synthesis, implying a role for DNA binding in their mechanism of action. Binding of the pyridine complexes to calf thymus DNA is, however, significantly less than for the analogous ammine complexes. The presence of trans-pyridine ligands results in steric hindrance, which retards the rate of reaction of trans-[PtCl2(pyridine)2], relative to trans[PtCl2(NH3)2], with other important biomols. such as glutathione. The results point to a potential new class of platinum antitumor complexes acting by a new mechanism and with activity complementary to agents such as cisplatin.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Research Support, N.I.H., Extramural, Research Support, Non-U.S. Gov’t, Nature Chemical Biology called Discovery and resistance mechanism of a selective CDK12 degrader, Author is Jiang, Baishan; Gao, Yang; Che, Jianwei; Lu, Wenchao; Kaltheuner, Ines H.; Dries, Ruben; Kalocsay, Marian; Berberich, Matthew J.; Jiang, Jie; You, Inchul; Kwiatkowski, Nicholas; Riching, Kristin M.; Daniels, Danette L.; Sorger, Peter K.; Geyer, Matthias; Zhang, Tinghu; Gray, Nathanael S., which mentions a compound: 882562-40-5, SMILESS is ClC1=NC(C2=CN(C3=C2C=CC=C3)S(=O)(=O)C2=CC=CC=C2)=C(Cl)C=N1, Molecular C18H11Cl2N3O2S, Name: 3-(2,5-Dichloropyrimidin-4-yl)-1-(phenylsulfonyl)-1H-indole.

Cyclin-dependent kinase 12 (CDK12) is an emerging therapeutic target due to its role in regulating transcription of DNA-damage response (DDR) genes. However, development of selective small mols. targeting CDK12 has been challenging due to the high degree of homol. between kinase domains of CDK12 and other transcriptional CDKs, most notably CDK13. In the present study, the rational design and characterization of a CDK12-specific degrader, BSJ-4-116 (I), is reported. BSJ-4-116 selectively degraded CDK12 as assessed through quant. proteomics. Selective degradation of CDK12 resulted in premature cleavage and poly(adenylation) of DDR genes. Moreover, BSJ-4-116 exhibited potent antiproliferative effects, alone and in combination with the poly(ADP-ribose) polymerase inhibitor olaparib, as well as when used as a single agent against cell lines resistant to covalent CDK12 inhibitors. Two point mutations in CDK12 were identified that confer resistance to BSJ-4-116, demonstrating a potential mechanism that tumor cells can use to evade bivalent degrader mols.

From this literature《Discovery and resistance mechanism of a selective CDK12 degrader》,we know some information about this compound(882562-40-5)Name: 3-(2,5-Dichloropyrimidin-4-yl)-1-(phenylsulfonyl)-1H-indole, but this is not all information, there are many literatures related to this compound(882562-40-5).

Assignments are given for the ir spectra of metal-pyridine complexes of the type NiX2.npy, CuX2.2py (X = Cl, Br; n = 1,2,4) and cis-, trans-PtCl2.2py in the 200-1610-cm-1 region. For a series of Ni complexes studied, the ν(Ni-N) vibrations occur at ∼240 cm-1. Cu complexes, on the other hand, show the ν(Cu-N) band near 270 cm-1. Among pyridine vibrations the ν4, ν9, ν10 and ν27, ring deformation vibrations, and the ν16, H in-plane deformation vibration, shift significantly to a higher frequency by complex formation. Among the rest, the ν10, in-plane ring deformation vibration, is the most sensitive upon complex formation.

The stereochem. properties of a variety of cis complexes of Pt(II) containing purine or pyrimidine ligands are examined The critical intramol. conformational parameters [the interbase dihedral angle and the base/coordination plane dihedral angles] are systematically studied and trends sought. Where intramol. interactions are determinative of the adopted mol. conformation, the nature of the steric demands imposed by increasing numbers of exocyclic functional groups contiguous to the Pt binding site are clearly of major importance for the antitumor activity.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions.

Keywords: EGFR activating gatekeeper mutant covalent inhibitor SAR. Let’s learn more about this compound (cas:882562-40-5).

A novel series of small-mol. inhibitors has been developed to target the double mutant form of the epidermal growth factor receptor (EGFR) tyrosine kinase, which is resistant to treatment with gefitinib and erlotinib. Our reported compounds also show selectivity over wild-type EGFR. Guided by mol. modeling, this series was evolved to target a cysteine residue in the ATP binding site via covalent bond formation and demonstrates high levels of activity in cellular models of the double mutant form of EGFR. In addition, these compounds show significant activity against the activating mutations, which gefitinib and erlotinib target and inhibition of which gives rise to their observed clin. efficacy. A glutathione (GSH)-based assay was used to measure thiol reactivity toward the electrophilic functionality of the inhibitor series, enabling both the identification of a suitable reactivity window for their potency and the development of a reactivity quant. structure-property relationship (QSPR) to support design.
