Quality Control of 1,4,5,6-Tetrahydro-pyrrolo[3,4-c]pyrazole,hydrochloride《CoREST Complex-Selective Histone Deacetylase Inhibitors Show Prosynaptic Effects and an Improved Safety Profile To Enable Treatment of Synaptopathies》 was published in 2019. The authors were Fuller, Nathan O.;Pirone, Antonella;Lynch, Berkley A.;Hewitt, Michael C.;Quinton, Maria S.;McKee, Timothy D.;Ivarsson, Magnus, and the article was included in《ACS Chemical Neuroscience》. The author mentioned the following in the article:

Synaptic dysfunction is a pathol. feature in many neurodegenerative disorders, including Alzheimer’s disease, and synaptic loss correlates closely with cognitive decline. Histone deacetylases (HDACs) are involved in chromatin remodeling and gene expression and have been shown to regulate synaptogenesis and synaptic plasticity, thus providing an attractive drug discovery target for promoting synaptic growth and function. To date, HDAC inhibitor compounds with prosynaptic effects are plagued by known HDAC dose-limiting hematol. toxicities, precluding their application to treating chronic neurol. conditions. We have identified a series of novel HDAC inhibitor compounds that selectively inhibit the HDAC-co-repressor of repressor element-1 silencing transcription factor (CoREST) complex while minimizing hematol. side effects. HDAC1 and HDAC2 associate with multiple co-repressor complexes including CoREST, which regulates neuronal gene expression. We show that selectively targeting the CoREST co-repressor complex with the representative compound Rodin-A results in increased spine d. and synaptic proteins, and improved long-term potentiation in a mouse model at doses that provide a substantial safety margin that would enable chronic treatment. The CoREST-selective HDAC inhibitor Rodin-A(I) thus represents a promising therapeutic strategy in targeting synaptic pathol. involved in neurol. disorders. The experimental procedure involved many compounds, such as 1,4,5,6-Tetrahydro-pyrrolo[3,4-c]pyrazole,hydrochloride (cas: 157327-47-4) .

Substituted pyrazoles are prepared by condensation of 1,3-diketones with hydrazine (Knorr-type reactions). For example, acetylacetone and hydrazine gives 3,5-dimethylpyrazole. Computed Properties of 2075-46-9.

Li, Bu-Tong;Li, Lu-Lin;Liu, Lin-Li research published 《 Thermal stability and detonation characters of nitro-substituted derivatives of pyrazole》, the research content is summarized as follows. A review. High-energy-d. compounds are designed successively by substituting the hydrogen atoms of 1H-pyrazole by the nitro group. The thermal stabilities are explored by the calculations of the heat of formation, bond orders, and bond dissociation energy at the B3PW91/6-311 + G(d,p) level. To evaluate the potential application as high-energy-d. compounds, the mol. d. (ρ), explosive heat (Q), the detonation velocity and detonation pressure are evaluated by using the empirical Kamlet-Jacobs equation. Based on our calculations, five mols. (3,4,5-trinitro-1H-pyrazole, 1,4,5-trinitro-1H-pyrazole, 1,3,5-trinitro-1H-pyrazole, 1,3,4-trinitro-1H-pyrazole, 1,3,4,5-tetranitro-1H-pyrazole) reached the balance between the stability and detonation characters and can be regarded as the potential high-energy-d. compounds

Computed Properties of 2075-46-9, 4-Nitro-1H-pyrazole, also known as 4-Nitropyrazole, is a useful research compound. Its molecular formula is C3H3N3O2 and its molecular weight is 113.08 g/mol. The purity is usually 95%.

4-Nitropyrazole, is a building block for the synthesis of various pharmaceutical compounds, including inhibitors, and therapeutic agents. It can be used for the synthesis of highly selective, brain-penetrant aminopyrazole LRRK2 Inhibitor, as a potentially viable treatment for Parkinson’s disease., 2075-46-9.
