In a Article，once mentioned of 34231-77-1

Various novel thiosemicarbazones (TSCs) 15b-e, 16b-e, 17b-e, 18b-e, and 19b-e derived from 4-pyridazinecarbaldehyde, 3-pyridazinecarbaldehyde, 4-acetylpyridazine, 3-acetylpyridazine, and 3-propionylpyridazine were prepared and their cytotoxic and antiherpetic potentials were evaluated. It was found that the replacement of the 2-pyridyl-moiety in aldehyde derived compounds 20a-c by a 4-pyridazinyl group (compounds 15b-d) abolishes biological activity. However, in TSCs derived from 3-pyridazinecarbaldehyde (16b-d) the cytotoxic potency was considerably reduced (factor ~300), while the antiviral activity was largely retained. A total loss of biological activity occurred when the pyridyl group in TSC 20d, derived from 2-acetylpyridine, was replaced by the 4-pyridazinyl system (17d). By employment of the 3-pyridazinyl unit for isosteric modification, however, the cell toxicity could be reduced significantly (factor 100) without impairing the antiherpetic potential also in the series of TSCs derived from N-heteroaromatic ketones. It was observed that there is no obvious influence of the size of the cycloamino substituent on the biological activities in compounds 20a-d, 15b-d, 16b-d, 17b-d, and 18b-d. While the pyridine derived TSCs in our experiments proved clearly cytotoxic at lower concentrations than those being antivirally active, the aza-analogous compounds derived from 3-acetyl-pyridazine (18b-e) inhibited plaque formation at concentrations equal to those causing cytotoxic effects. The TSCs 16b-e derived from 3-pyridazinecarbaldehyde were found to show selective antiviral activity against HSV-1. In addition, a significant improvement of the water solubility of heteroaromatic TSCs could be achieved by the replacement of the CH-moiety in position 6 of the pyridine derivatives 20a-c by a nitrogen atom (compounds 16b-d).

The description relates to cereblon E3 ligase binding compounds, including bifunctional compounds comprising the same, which find utility as modulators of targeted ubiquitination, especially inhibitors of a variety of polypeptides and other proteins which are degraded and/or otherwise inhibited by bifunctional compounds according to the present disclosure. In particular, the description provides compounds, which contain on one end a ligand which binds to the cereblon E3 ubiquitin ligase and on the other end a moiety which binds a target protein such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of that protein. Compounds can be synthesized that exhibit a broad range of pharmacological activities consistent with the degradation/inhibition of targeted polypeptides of nearly any type.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Related Products of 141-30-0. Introducing a new discovery about 141-30-0, Name is 3,6-Dichloropyridazine

Four organic-inorganic hybrid complexes ([(HL1)2SnCl 6]·2H2O (1) (L1=2-methylquinoline), [(HL2) 2(CdCl4)]·2H2O (2) (L2=5,7-dimethyl-1,8- naphthyridine-2-amine), [(H2L2)2SnCl6]2(Cl) (3), and [(H2L3)SnCl6]·2H2O (4) (L3=3,6-bis(imidazol-1-yl)pyridazine)) derived from N-containing aromatic Brnsted bases and metal(II) chloride dihydrate (tin(II) chloride dihydrate and cadmium(II) chloride dihydrate) were prepared and characterized by IR, X-ray structure analysis, elemental analysis, and TG analysis. The aromatic rings of the cations in all of the compounds are essentially planar. X-ray diffraction analysis revealed that 2-4 have 3-D network structures built from hydrogen bonds between the cations and chlorometallates. Water molecules also play important roles in structure extension in 1, 2, and 4. The arrangements of the anions and cations in their solid state are dominated by shape, size, and symmetry of the cations and the different structures of the chlorometallates as well as by hydrogen-bond interactions.
