- Hydroxy-Substituted Heteroarylpiperazines: Novel Scaffolds for β-Arrestin-Biased D2R Agonists
-
By means of a formal structural hybridization of the antipsychotic drug aripiprazole and the heterocyclic catecholamine surrogates present in the β2-adrenoceptor agonists procaterol and BI-167107 (4), we designed and synthesized a collection of novel hydroxy-substituted heteroarylpiperazines and heteroarylhomopiperazines with high dopamine D2 receptor (D2R) affinity. In contrast to the weak agonistic behavior of aripiprazole, these ligands are capable of effectively mimicking those interactions of dopamine and the D2R that are crucial for an active state, leading to the recruitment of β-arrestin-2. Interestingly, some ligands show considerably lower intrinsic activity in guanine nucleotide exchange experiments at D2R and consequently represent biased agonists favoring β-arrestin-2 recruitment over canonical G protein activation. The ligands' agonistic properties are substantially driven by the presence of an endocyclic H-bond donor.

- Synthesis and inhibitory activity of new ethylenedioxyquinones as analogs of coenzyme
-
A new series of analogs of coenzyme Q, 2,3 ethylenedioxy 5 hydroxy 6 alkyl 1,4 benzoquinones, was synthesized on the basis of the minor differences in the electronic and rotational nature between the 2,3 ethylenedioxy group and 2,3 dimethoxy groups. These differences could affect the redox potential of the 1,4 benzoquinone and, in turn, affect inhibitory activity. The 6 alkyl groups were farnesyl, phytyl, nonyl, decyl, pentadecyl, heptadecyl, and 5' (cyclohexyl)pentyl. The succinoxidase and DPNH oxidase systems of intact mitochondria from beef heart were used in tests for inhibition. The nonyl, decyl, pentadecyl, and farnesyl analogs showed inhibitions of less than 40%; and the phytyl, heptadecyl, and 5' (cyclohexyl)pentyl analogs showed inhibitions of about 50% in succinoxidase. All the analogs were less inhibitory in DPNH oxidase. 2,3 Dimethoxy 5 hydroxy 6 n pentadecyl 1,4 benzoquinone showed 91% inhibition at a concentration of 97 nmol of inhibitor/mg of mitochondrial protein, while 2,3 ethylenedioxy 5 hydroxy 6 n pentadecyl 1,4 benzoquinone exhibited only 37% inhibition at the higher concentration of 140 nmol of inhibitor/mg of mitochondrial protein in the succinoxidase system. Similarly, this 2,3 dimethoxyquinone was a more potent inhibitor in DPNH oxidase. 2,3 Dimethoxy 5 hydroxy 6 n pentadecyl 1,4 benzoquinone showed 91% inhibition at a concentration of 97 nmol of inhibitor/mg of mitochondrial protein, while 2,3 ethylenedioxy 5 hydroxy 6 n pentadecyl 1,4 benzoquinone exhibited only 37% inhibition at the higher concentration of 140 nmol of inhibitor/mg of mitochondrial protein in the succinoxidase system. Similarly, this 2,3 dimethoxyquinone was a more potent inhibitor in DPNH oxidase than the corresponding 2,3 ethylenedioxyquinone. Apparently, 2,3 dimethoxy groups are more favorable than the 2,3 ethylenedioxy group on the 5 hydroxy 6 alkyl 1,4 benzoquinone nucleus for inhibition of these two CoQ oxidases.

- Studies toward the discovery of the next generation of antidepressants. 3. Dual 5-HT1A and serotonin transporter affinity within a class of N-aryloxyethylindolylalkylamines
-
N-Aryloxylethylindolealkylamines (5) having dual 5-HT transporter and 5-HT1A affinity are described. These compounds represent truncated analogues of our previously reported piperidinyl derivatives (3). Compounds in this investigation were found to have more similar affinities and functional activities for the 5-HT1A receptor and 5-HT transporter. Though 5-HT1A antagonism is not consistently observed throughout series 5, several molecular features were found to be essential to obtain high and balanced activities. The proper placement of a heteroatom in the aryl ring and the length of the linkage used to tether the indole moiety had significant influence on 5-HT1A and 5-HT transporter affinities. Introduction of a halogen into the aryl ring usually lowered intrinsic activity and in some cases led to full 5-HT1A antagonists. Compounds 33 and 34 were observed to be full 5-HT1A antagonists with Ki values of approximately 30 nM for the 5-HT1A receptor and Ki values of 5 and 0.5 nM for the 5-HT transporter, respectively. Unfortunately, similar to our previous series (3), compounds in this report also had high affinity for the α1 receptor.

- Synthesis and Characterization of Crowned 1,4-Benzoquinones as Ionophore-Dienophile (Redox) Combined Systems: Double Interaction with Catecholamines and Tryptamine
-
The crowned 1,4-benzoquinones (1) (15-crown-5) and (2) (18-crown-6) have been synthesized from pyrogallol (3) by: (1) the selective monobenzylation (4); (2) crown ether formation using a pyrocatechols (5) and (6); (3) debenzylation (7) and (8); and (4) oxidation to 1,4-benzoquinones.Both compounds (1) and (2) underwent smooth Diels-Alder reactions with cyclopentadiene (25 deg C), thebaine (80 deg C), and buta-1,3-diene (BF3*Et2O, 0 deg C).The cyclopentadiene adducts (11) and (12) were photochemically transformed into the cage compounds (13) and (14), while the thebaine adducts (15) and (16) were smoothly converted into the hydroquinone derivatives (17) and (18) by silicic acid.The butadiene adducts (19) and (20) were transformed into the crowned naphthoquinones (23) and (24) in high yields.The redox potentials of these crowned quinones in the presence of alkali-metal ions were studied by cyclic voltammetry.The specific interaction between compound (2) and tryptamine, dopamine, and homoveratrylamine via ion-binding and charge-transfer complex formation was evidenced by u.v. spectroscopic studies.
