Phenylpiperazine type UBE2F small molecule inhibitor and synthesis method thereof

The invention discloses a phenylpiperazine type UBE2F small molecule inhibitor and a synthesis method thereof, discloses a phenylpiperazine type compound represented by the general formula I or a pharmaceutically acceptable salt thereof, and further discloses a synthesis route of the general formula I and a synthesis method of each step. As a small molecule inhibitor target at UBE2F, that phenylpiperazine type compound of the present invention effectively suppresses the growth of tumor cell by preventing the G2/M process of cell cycle and inducing apoptosis of human tumor cells. Therefore, thecompound is a new class of specific anti-tumor drugs by targeting UBE2F.

NMR-based investigations of acyl-functionalized piperazines concerning their conformational behavior in solution

Selected N-benzoylated piperazine compounds were synthesized to study their conformational behavior using temperature-dependent 1H NMR spectroscopy. All investigated piperazines occur as conformers at room temperature resulting from the restric

Functionalized acridin-9-yl phenylamines protected neuronal HT22 cells from glutamate-induced cell death by reducing intracellular levels of free radical species

The in vitro neuronal cell death model based on the HT22 mouse hippocampal cell model is a convenient means of identifying compounds that protect against oxidative glutamate toxicity which plays a role in the development of certain neurodegenerative diseases. Functionalized acridin-9-yl-phenylamines were found to protect HT22 cells from glutamate challenge at submicromolar concentrations. The Aryl1-NHAryl2 scaffold that is embedded in these compounds was the minimal pharmacophore for activity. Mechanistically, protection against the endogenous oxidative stress generated by glutamate did not involve up-regulation of glutathione levels but attenuation of the late stage increases in mitochondrial ROS and intracellular calcium levels. The NH residue in the pharmacophore played a crucial role in this regard as seen from the loss of neuroprotection when it was structurally modified or replaced. That the same NH was essential for radical scavenging in cell-free and cell-based systems pointed to an antioxidant basis for the neuroprotective activities of these compounds.

Design, synthesis and pharmacological evaluation of N-[4-(4-(alkyl/aryl/heteroaryl)-piperazin-1-yl)-phenyl]-carbamic acid ethyl ester derivatives as novel anticonvulsant agents

A series of alkyl/aryl/heteroaryl piperazine derivatives (37-54) were designed and synthesized as potential anticonvulsant agents. The target compounds are endowed with satisfactory physicochemical as well as pharmacokinetic properties. The synthesized compounds were screened for their in vivo anticonvulsant activity in maximal electroshock (MES) and subcutaneous pentylenetetrazole (sc-PTZ) seizure tests. Further, neurotoxicity evaluation was carried out using rotarod method. Structure activity relationship studies showed that compounds possessing aromatic group at the piperazine ring displayed potent anticonvulsant activity. Majority of the compounds showed anti-MES activity whereas compounds 39, 41, 42, 43, 44, 50, 52, and 53 exhibited anticonvulsant activity in both seizure tests. All the compounds except 42, 46, 47, and 50 did not show neurotoxicity. The most active derivative, 45 demonstrated potent anticonvulsant activity in MES test at the dose of 30 mg/kg (0.5 h) and 100 mg/kg (4 h) and also delivered excellent protection in sc-PTZ test (100 mg/kg) at both time intervals. Therefore, compound 45 was further assessed in PTZ-kindling model of epilepsy which is widely used model for studying epileptogenesis. This compound was effective in delaying onset of PTZ-evoked seizures at the dose of 5 mg/kg in kindled animals and significantly reduced oxidative stress better than standard drug phenobarbital (PB). In result, compound 45 emerged as a most potent and safer anticonvulsant lead molecule.

Synthesis of a novel, recyclable, solid-phase acylating reagent.

In this paper, we describe the synthesis of N-(6-cyano-1,3-dimethyl-2,4-dioxo-5-substituted-1,3-dihydropyridino[2,3-d] pyrimidin-7-yl)imides 1. We will show the synthesis of 1 using both conventional heating and microwave techniques. In addition, the imide was attached to polystyrene and this immobilized imide was equally as effective at acylating various primary and secondary amines as its solution-phase counterpart.
