Metal?organic frameworks (MOFs), as a new class of porous solid materials, have emerged and their study has established itself very quickly into a productive research field. This short review recaps the recent advancement of chiral MOFs. Here, we present simple, well-ordered instances to classify the mode of synthesis of chiral MOFs, and later demonstrate the potential applications of chiral MOFs in heterogeneous asymmetric catalysis and enantioselective separation. The asymmetric catalysis sections are subdivided based on the types of reactions that have been successfully carried out recently by chiral MOFs. In the part on enantioselective separation, we present the potentiality of chiral MOFs as a stationary phase for high-performance liquid chromatography (HPLC) and high-resolution gas chromatography (GC) by considering fruitful examples from current research work. We anticipate that this review will provide interest to researchers to design new homochiral MOFs with even greater complexity and effort to execute their potential functions in several fields, such as asymmetric catalysis, enantiomer separation, and chiral recognition.

A mild and highly efficient metal-free oxidative alpha-cyanation of N-acyl/sulfonyl 1,2,3,4-tetrahydroisoquinolines (THIQs) has been accomplished at an ambient temperature via DDQ oxidation and subsequent trapping of N-acyl/sulfonyl iminium ions with (n-Bu)3SnCN. Employing readily removable N-acyl/sulfonyl groups as protecting groups rather than N-aryl ones enables a wide range of applications in natural product synthesis. The synthetic utility of the method was illustrated using a short and efficient formal total synthesis of (±)-calycotomine in three steps.

Despite their uncertain identification, sigma2 receptors are promising targets for the development of diagnostics and therapeutics for tumor diseases. Among the sigma2 ligands developed, the class of the flexible benzamides furnished an optimal pharmacophore for sigma2 receptor high affinity ligands. A recent investigation suggested that flexible benzamides bind sigma2 receptors in a bicyclic-like conformation due to an intramolecular H-bond, with 3,4-dihydroisoquinolinone derivatives reaching excellent sigma2 affinity and selectivity. Herein, the bicyclic-preferred conformation for sigma2 binding was confirmed through the development of 3,4-dihydroquinolin-(1H)2-one isomeric derivatives, 1,2,3,4-tetrahydroquinolines and the corresponding flexible anilides and anilines, all linked to the 6,7-dimethoxytetrahydroisoquinoline as a basic moiety. 3,4-Dihydroisoquinolin-(1H)2-one (10a) and 1,2,3,4-tetrahydroisoquinoline (11b) emerged for high sigma2 affinity combined to an excellent sigma2versus sigma1 selectivity. In particular, compound 11b with its low nanomolar sigma2 affinity and impressive 2807-fold sigma2versus sigma1 selectivity largely exceeded the biological profile of the best 3,4-dihydroisoquinolin-(2H)1-one reference compounds (1). Because of the absence of a cytotoxic effect, the modest interaction with the P-gp, an appropriate lipophilicity and the presence of easily radiolabeling functions, 11b deserves further investigation for the imaging of sigma2 receptors via PET in tumors.

The prion diseases caused by PrPSc, an alternatively folded form of the cellular prion protein (PrPC), are rapidly progressive, fatal, and untreatable neurodegenerative disorders. We employed HTS ELISA assays to identify compounds that lower the level of PrPSc in prion-infected mouse neuroblastoma (ScN2a-cl3) cells and identified a series of arylamides. Structure-activity relationship (SAR) studies indicated that small amides with one aromatic or heteroaromatic ring on each side of the amide bond are of modest potency. Of note, benzamide (7), with an EC50 of 2200 nM, was one of only a few arylamide hits with a piperazine group on its aniline moiety. The basic piperazine nitrogen can be protonated at physiologic pH, improving solubility, and therefore, we wanted to exploit this feature in our search for a drug candidate. An SAR campaign resulted in several key analogues, including a set with biaryl groups introduced on the carbonyl side for improved potency. Several of these biaryl analogues have submicromolar potency, with the most potent analogue 17 having an EC50 = 22 nM. More importantly, 17 and several biarylamides (20, 24, 26, and 27) were able to traverse the blood-brain barrier (BBB) and displayed excellent drug levels in the brains of mice following oral dosing. These biarylamides may represent good starting points for further lead optimization for the identification of potential drug candidates for the treatment of prion diseases.

P-Glycoprotein (P-gp), along with other transporter proteins at the blood-brain barrier (BBB), limits the entry of many pharmaceuticals into the brain. Altered P-gp function has been found in several neurological diseases. To study the P-gp function, many positron emission tomography (PET) radiopharmaceuticals have been developed. Most P-gp radiopharmaceuticals are labeled with carbon-11, while labeling with fluorine-18 would increase their applicability due to longer half-life. Here we present the synthesis and in vivo evaluation of three novel fluorine-18 labeled radiopharmaceuticals: 4-((6,7-dimethoxy-3,4-dihydroisoquinolin-2(1H)-yl)methyl)-2-(4-fluorophenyl)oxazole (1a), 2-biphenyl-4-yl-2-fluoroethoxy-6,7-dimethoxy-1,2,3,4-tetrahydro-isoquinoline (2), and 5-(1-(2-fluoroethoxy))-[3-(6,7-dimethoxy-3,4-dihydro-1H-isoquinolin-2-yl)-propyl]-5,6,7,8-tetrahydronaphthalen (3). Compounds were characterized as P-gp substrates in vitro, and Mdr1a/b(-/-)Bcrp1(-/-) and wild-type mice were used to assess the substrate potential in vivo. Comparison was made to (R)-[11C]verapamil, which is currently the most frequently used P-gp substrate. Compound [18F]3 was performing the best out of the new radiopharmaceuticals; it had 2-fold higher brain uptake in the Mdr1a/b(-/-)Bcrp1(-/-) mice compared to wild-type and was metabolically quite stable. In the plasma, 69% of the parent compound was intact after 45 min and 96% in the brain. Selectivity of [18F]3 to P-gp was tested by comparing the uptake in Mdr1a/b(-/-) mice to uptake in Mdr1a/b(-/-)Bcrp1(-/-) mice, which was statistically not significantly different. Hence, [18F]3 was found to be selective for P-gp and is a promising new radiopharmaceutical for P-gp PET imaging at the BBB. (Chemical Equation).
