Comparative molecular field analysis (CoMFA) models of phenylethanolamine N-methyltransferase (PNMT) and the alpha2-adrenoceptor: The development of new, highly selective inhibitors of PNMT

As a guide to the development of new and more selective inhibitors of phenylethanolamine N-methyltransferase (PNMT) vs the alpha2-adrenoceptor, we have performed a comparative molecular field analysis (CoMFA) on a series of 80 benzylamine analogues. Using the models obtained, we have proposed a series of 3-trifluoromethyl-1,2,3,4-tetrahydroisoquinolines and predicted the activity of other analogues.

Metal-Free Synthesis of N-Aryl Amides using Organocatalytic Ring-Opening Aminolysis of Lactones

Catalytic ring-opening of bio-sourced non-strained lactones with aromatic amines can offer a straightforward, 100 % atom-economical, and sustainable pathway towards relevant N-aryl amide scaffolds. Herein, the first general, metal-free, and highly efficient N-aryl amide formation is reported from poorly reactive aromatic amines and non-strained lactones under mild operating conditions using an organic bicyclic guanidine catalyst. This protocol has high application potential as exemplified by the formal syntheses of drug-relevant molecules.

Fluorinated betulinic acid derivatives and evaluation of their anti-HIV activity

Several fluorinated derivatives of the anti-HIV maturation agent bevirimat (1) were synthesized and evaluated for anti-HIV replication activity. The modified positions were the C-2, C-3, C-28, and C-30 positions, either directly on the betulinic acid (2) skeleton or in the attached side chains. Compound 18, which has a trifluoromethyl group added to C-30 of its isopropenyl group, exhibited similar potency to 1 against HIV-1NL4-3. In total, our current studies support our prior conclusion that C-30 allylic modification is unlikely to be a pharmacophore for anti-HIV activity, but could be a meaningful route to manipulate other properties of 2-related compounds.

Study on the total synthesis of velbanamine: Chemoselective dioxygenation of alkenes with PIFA via a stop-and-flow strategy

A “stop-and-flow” strategy was developed for the chemoselective dioxygenation of alkenes with a PIFA-initiated cyclization. This method is conceived for the desymmetrization of seco-diene, and a series of substituted 5-hydroxymethyl-gamma-lactones were constructed after hydrolysis. This strategy also differentiates terminally substituted alkenes and constitutes a potentially novel synthetic approach for the efficient synthesis toward velbanamine.

Arylamides hybrids of two high-affinity sigma2 receptor ligands as tools for the development of PET radiotracers

1-Cyclohexyl-4-[3-(5-methoxy-1,2,3,4-tetrahydronaphthalen-1-yl)propyl] piperazine 1 (PB28) and 2-Methoxy-5-methyl-N-[4-(6,7-dimethoxy-3,4-dihydro-1H- isoquinolin-2-yl)butyl]benzamide 2 (RHM-1) represent leads for tumor diagnosis, given their high affinity at sigma2 receptors. With the purpose of obtaining good candidates for sigma2 PET tracers development, hybrid structures between 1 and 2 were designed. Excellent sigma1/ sigma2 selectivities were reached when 6,7- dimethoxytetrahydroisoquinoline was linked to an o-methoxy substituted arylamide (11a, 12a, 15a), and for these benzamides an intramolecular H-bond in the active conformation at the sigma sites, was hypothesized. However these excellent sigma2 ligands were accompanied by interaction with P-gp, which may limit their use as sigma2 receptor PET agents when tumors overexpress P-gp. Compound 15a whose P-gp interaction was just moderate represents an interesting tool for the development of sigma2 PET tracers useful in tumors overexpressing P-gp.

1-magnesiotetrahydroisoquinolyloxazolines as chiral nucleophiles in stereoselective additions to aldehydes: Auxiliary optimization, asymmetric synthesis of (+)-corlumine, (+)-bicuculline, (+)-egenine, and (+)-corytensine, and preliminary 13C NMR studies of 1-lithio- and 1-magnesiotetrahydroisoquinolyloxazolines

Transmetalation of 1-lithiotetrahydroisoquinolyloxazolines with magnesium halides affords Grignard reagents that add to aldehydes with up to 80% selectivity for one of the four possible diastereomeric products. An oxazoline chiral auxiliary derived from camphor provides an optimal blend of diastereoselectivity and isomer separability. Synthetic applications of the optimal auxiliary, patterned after a literature approach in the racemic series, comprise an improved (formal) synthesis of bicuculline, egenine, and corytensine, as well as an efficient synthesis of corlumine. Preliminary NMR studies show that both 1-lithio- and 1-magnesiotetrahydroisoquinolyloxazolines are dynamic mixtures in THF solution at low temperatures. The barrier to pyramidal inversion of the secondary Grignard reagent is in the 9.8-10.1 kcal/mol range, while an upper limit of about 8.2 kcal/mol can be assigned to the barrier to the organolithium inversion.
