    Resourceful synthesis of pyrazolo[1,5-a]pyrimidines under ultrasound irradiation
    摘要:
    Pyrazolo[1,5-a]pyrimidines were synthesized via the ultrasonic sonochemical method using the cyclo-condensation reaction of 4-alkoxy-1,1,1-trifluoro-3-alken-2-ones [CF3(C)(O)CH = C(R)(OMe) - where R = Me, Bu, i-Bu, Ph, 4-Me-C6H4, 4-F-C6H4, 4-CI-C6H4, 4-Br-C6H4, naphth-2-yl and biphen-4-yl] - with 3-amino-5-methyl-1H-pyrazole in the presence of EtOH for 5 min. This methodology has several advantages, for example, it is a simple procedure, it has an easy work-up, Mild conditions, short reaction times (5 min) and produces satisfactory yields (61-98%).

    Selective thiocyanation (yield 70–90%) at the 3-position of pyrazolo[1,5- a ]pyrimidines was performed with thiocyanogen electrochemically generated in situ from NH 4 SCN in MeCN on a Pt anode. For substrates with higher oxidation potential addition of Lewis acids was necessary.

    An effective system of approaches to electrooxidative C–H thiocyanation of both high and low reactive pyrazolo[1,5‐a]pyrimidines under mild conditions has been proposed for the first time. The process scaling up, the antifungal activity of resulting thiocyanates, and possibility of their transformation into thiols also demonstrate advantages and viability of this direct C–S coupling strategy. In general
    首次提出了在温和条件下有效反应高和低反应性吡唑并[1,5- a ]嘧啶的C–H硫氰化方法的有效体系。规模扩大的过程,所得硫氰酸盐的抗真菌活性以及将其转化为硫醇的可能性也证明了这种直接C-S偶联策略的优势和可行性。通常,温和的反应条件和高的C–S键形成效率使这种基于吡唑并[1,5- a ]嘧啶的电氧化C–H硫氰化的策略在未来的应用中非常可行。

  • REPORTER SYSTEM FOR HIGH THROUGHPUT SCREENING OF COMPOUNDS AND USES THEREOF

    The NF-E2-related factor 2 (Nrf2) is a key transcriptional regulator of antioxidant defense and detoxification. To directly monitor stabilization of Nrf2 we fused its Neh2 domain, responsible for the interaction with its nucleocytoplasmic regulator, Keap1, to firefly luciferase (Neh2-luciferase). It is shown herein that Neh2 domain is sufficient for recognition, ubiquitination and proteasomal degradation of Neh2-luciferase fusion protein. The novel Neh2-luc reporter system allows direct monitoring of the adaptive response to redox stress and classification of drugs based on the time-course of reporter activation. The novel reporter was used to screen a library of compounds to identify activators of Nrf2. The most robust and yet non toxic Nrf2 activators found—nordihydroguaiaretic acid, fisetin, and gedunin-induced astrocyte-dependent neuroprotection from oxidative stress via an Nrf2-dependent mechanism.
