The development of 2-acetylphenol-donepezil hybrids as multifunctional agents for the treatment of Alzheimer’s disease

A series of 2-acetylphenol-donepezil hybrids was designed and synthesized based on multi-target-directed ligands strategy. The biological activities were evaluated by AChE/BChE inhibition and MAO-A/MAO-B inhibition. The results revealed that the tertiary amines and methylene chain length significantly affected the eeAChE inhibitory potency, in particular, compound TM-14 showed the best eeAChE inhibitory activity with IC50 value of 2.9 muM, in addition, both kinetic analysis of AChE inhibition and docking study displayed that TM-14 could simultaneously bind to the catalytic active site and peripheral anionic site of AChE. Moreover, compound TM-14 was a selective metal chelator and could form 1:1 TM-14-Cu2+ complex. The structure-active-relationship also indicated that the O-alkylamine fragment remarkably decreased hMAO-B inhibitory activity, compound TM-2 exhibited potent hMAO-B inhibitory activity (IC50 = 6.8 muM), which was supported by the molecular docking study. More interestingly, compounds TM-14 and TM-2 could cross the blood-brain barrier in vitro. Therefore, the structure-active-relationship of 2-acetylphenol-donepezil hybrids could encourage the development of multifunction agents with selective AChE inhibition or selective MAO-B inhibition for the treatment of Alzheimer’s disease.

Controllable Chemoselectivity in Visible-Light Photoredox Catalysis: Four Diverse Aerobic Radical Cascade Reactions

Reported is the controllable selectivity syntheses of four distinct products from the same starting materials by visible-light photoredox catalysis. By employing a dicyanopyrazine-derived chromophore (DPZ) as photoredox catalyst, an aerobic radical mechanism has been developed, and allows the reactions of N-tetrahydroisoquinolines (THIQs) with N-itaconimides to through four different pathways, including addition-cyclization, addition-elimination, addition-coupling, and addition-protonation, with satisfactory chemoselectivity. The current strategy provide straightforward access to four different but valuable N-heterocyclic adducts in moderate to excellent yields. Radical control: A radical mechanism for N-tetrahydroisoquinolines (THIQ) in the presence of oxygen was successfully accomplished by employing a dicyanopyrazine-derived chromophore (DPZ) as a photoredox catalyst. The substrates can undergo either addition-cyclization, addition-elimination, addition-coupling, or addition-protonation by judiciously regulating the reaction conditions. Four types of N-heterocycles are generated in moderate to excellent yields.

3-(3,4-dihydroisoquinolin-2(1 H)-ylsulfonyl)benzoic acids: Highly potent and selective inhibitors of the type 5 17-beta-hydroxysteroid dehydrogenase AKR1C3

A high-throughput screen identified 3-(3,4-dihydroisoquinolin-2(1H)- ylsulfonyl)benzoic acid as a novel, highly potent (low nM), and isoform-selective (1500-fold) inhibitor of aldo-keto reductase AKR1C3: a target of interest in both breast and prostate cancer. Crystal structure studies showed that the carboxylate group occupies the oxyanion hole in the enzyme, while the sulfonamide provides the correct twist to allow the dihydroisoquinoline to bind in an adjacent hydrophobic pocket. SAR studies around this lead showed that the positioning of the carboxylate was critical, although it could be substituted by acid isosteres and amides. Small substituents on the dihydroisoquinoline gave improvements in potency. A set of “reverse sulfonamides” showed a 12-fold preference for the R stereoisomer. The compounds showed good cellular potency, as measured by inhibition of AKR1C3 metabolism of a known dinitrobenzamide substrate, with a broad rank order between enzymic and cellular activity, but amide analogues were more effective than predicted by the cellular assay.

Total synthesis of (-)-tetrahydropalmatine via chiral formamidine carbanions: Unexpected behavior with certain ortho-substituted electrophiles

A method has been developed by alkylation of chiral lithioformamidines to construct protoberberine alkaloids with a C(9) and C(10) D-ring substitution pattern. This ring pattern was established using an ortho-substituted hydroxymethylbenzene electrophile protected as a silyl ether to ultimately provide (-)-tetrahydropalmatine in 88% ee. Additionally, we have discovered limitations with ortho-substituted electrophiles in the asymmetric formamidine alkylation. These electrophiles have the potential to disrupt the lithium formamidine chelate and cause the selectivity in the alkylation to be uncharacteristically low. The total synthesis of (¡À)-canadine and (-)-tetrahydropalmatine along with the limitations to the formamidine alkylation technology are delineated herein.

Design, synthesis, and antifungal activities in vitro of novel tetrahydroisoquinoline compounds based on the structure of lanosterol 14alpha-demethylase (CYP51) of fungi

Novel tetrahydroisoquinoline compounds were designed by coupling structure-based de novo design based on the structure of lanosterol 14alpha-demethylase (CYP51). The chemical synthesis and the antifungal activities in vitro of them were reported. The results exhibited that all of the lead compounds showed potent antifungal activities, in which compounds 6 and 7 had equal or stronger antifungal activities against five test fungi than that of fluconazole. The studies presented here provided the antifungal lead compounds. The affinity of the lead molecules for CYP51 was mainly attributed to their non-bonding interaction with the apoprotein, which was different from the azole antifungal agents.

Benzamidobenzoic acids as potent PqsD inhibitors for the treatment of Pseudomonas aeruginosa infections

Targeting PqsD is a promising novel approach to disrupt bacterial cell-to-cell-communication in Pseudomonas aeruginosa. In search of selective PqsD inhibitors, two series of benzamidobenzoic acids – one published as RNAP inhibitors and the other as PqsD inhibitors – were investigated for inhibitory activity toward the respective other enzyme. Additionally, novel derivatives were synthesized and biologically evaluated. By this means, the structural features needed for benzamidobenzoic acids to be potent and, most notably, selective PqsD inhibitors were identified. The most interesting compound of this study was the 3-Cl substituted compound 5 which strongly inhibits PqsD (IC 50 6.2 muM) while exhibiting no inhibition of RNAP.
