New 1,2,3,4-tetrahydroisoquinoline derivatives as modulators of proteolytic cleavage of amyloid precursor proteins

A type of new 1,2,3,4-tetrahydroisoquinoline derivatives was synthesized via concise procedure from commercially available tetrahydroisoquinoline. These derivatives were delicately designed to possess propargyl-related pharmacophores simulated with a monoamine oxidase inhibitor rasagiline. We investigated the effect of these synthetic tetrahydroisoquinoline derivatives on the regulation of proteolytic processing of amyloid precursor protein (APP) by an ERK-dependent signaling pathway. Additionally, these compounds were also evaluated on the prevention of the proteolytic processing of C99 as γ-secretase inhibitors by using a highly efficient cell-based reporter gene assay for γ-secretase. The results suggested that certain compounds might be explored to possess both sAPPα-releasing stimulation and γ-secretase inhibitory potency, which may reflect the synergetic potential of neuroprotective activities for the treatment of Alzheimer's disease as they possessed both ERK activation and inhibition of amyloidogenic Aβ release.

Electrochemical approach to trifluoroacetamide synthesis from 1,1,1-trichloro-2,2,2-trifluoroethane (CFC-113a) catalyzed by B12complex

One-pot synthetic approach to produce trifluoroacetamide has been developed using an electrochemical method with the B12 complex as a catalyst under mild conditions, in open air at room temperature. Thirty examples of trifluoroacetamide were synthesized from 1,1,1-trichloro-2,2,2-trifluoroethane (CFC-113a) in moderate to good yields. This user-friendly strategy is compatible with a broad range of trifluoroacetamide syntheses.

N-(Pyrimidin-2-yl)-1,2,3,4-tetrahydroisoquinolin-6-amine Derivatives as Selective Janus Kinase 2 Inhibitors for the Treatment of Myeloproliferative Neoplasms

In this study, we described a series of N-(pyrimidin-2-yl)-1,2,3,4-tetrahydroisoquinolin-6-amine derivatives as selective JAK2 (Janus kinase 2) inhibitors. Systematic exploration of the structure-activity relationship though cyclization modification based on previously reported compound 18e led to the discovery of the superior derivative 13ac. Compound 13ac showed excellent potency on JAK2 kinase, SET-2, and Ba/F3V617F cells (high expression of JAK2V617F mutation) with IC50 values of 3, 11.7, and 41 nM, respectively. Further mechanistic studies demonstrated that compound 13ac could downregulate the phosphorylation of downstream proteins of JAK2 kinase in cells. Compound 13ac also showed good selectivity in kinase scanning and potent in vivo antitumor efficacy with 82.3% tumor growth inhibition in the SET-2 xenograft model. Moreover, 13ac significantly ameliorated the disease symptoms in a Ba/F3-JAK2V617F allograft model, with 77.1% normalization of spleen weight, which was more potent than Ruxolitinib.

Synthesis of trifluoromethyl moieties by late-stage copper (I) mediated nucleophilic fluorination

The nucleophilic fluorination of bromodifluoromethyl derivatives mediated by the complex (PPh3)3CuF is described. Under the reaction conditions, different trifluoroacetates, trifluoroketones, trifluoroarenes and trifluoroacetamides were obtained in good yields.

Efficient DBU accelerated synthesis of 18F-labelled trifluoroacetamides

Nucleophilic 18F-fluorination of bromodifluoromethyl derivatives was performed using [18F]Bu4NF in the presence of DBU (1,8-diazabicyclo[5.4.0]undec-7-ene). This novel procedure provided a diverse set of [18F]trifluoroacetamides in good to excellent radiochemical conversions. A mechanism where DBU acts as organomediator in this transformation is proposed.

An efficient and convenient synthesis of acyl coa: Monoacylglycerol acyltransferase 2 inhibitor, 2-[2-(4-tert-butylphenyl)ethyl]-N-[4-(3-cyclopentylpropyl)-2-fluorophenyl]-1,2,3,4-tetrahydroisoquinoline-6-sulfonamide

The optimized route consists of an effective chlorosulfonylation and debromination, resulting in an increase in the total yield from 6.8% to 45%, compared with our previous method. This synthetic approach enabled the synthesis of 1 to be scaled-up to a multi-gram scale.
