The Mpro structure-based modifications of ebselen derivatives for improved antiviral activity against SARS-CoV-2 virus

The main protease (Mpro or 3CLpro) of SARS-CoV-2 virus is a cysteine enzyme critical for viral replication and transcription, thus indicating a potential target for antiviral therapy. A recent repurposing effort has identified ebselen, a multifunctional drug candidate as an inhibitor of Mpro. Our docking of ebselen to the binding pocket of Mpro crystal structure suggests a noncovalent interaction for improvement of potency, antiviral activity and selectivity. To test this hypothesis, we designed and synthesized ebselen derivatives aimed at enhancing their non-covalent bonds within Mpro. The inhibition of Mpro by ebselen derivatives (0.3 μM) was screened in both HPLC and FRET assays. Nine ebselen derivatives (EBs) exhibited stronger inhibitory effect on Mpro with IC50 of 0.07–0.38 μM. Further evaluation of three derivatives showed that EB2-7 exhibited the most potent inhibition of SARS-CoV-2 viral replication with an IC50 value of 4.08 μM in HPAepiC cells, as compared to the prototype ebselen at 24.61 μM. Mechanistically, EB2-7 functions as a noncovalent Mpro inhibitor in LC-MS/MS assay. Taken together, our identification of ebselen derivatives with improved antiviral activity may lead to developmental potential for treatment of COVID-19 and SARS-CoV-2 infection.

Synthesis of 3-Alkylideneisoindolin-1-ones via Sonogashira Cyclocarbonylative Reactions of 2-Ethynylbenzamides

Cyclocarbonylative Sonogashira reactions of ortho-ethynylbenzamides have been investigated. The process is carried out under CO pressure, in the presence of a very small amount of PdCl2(PPh3)2 (0.4 mol %) as a catalytic precursor and without the need for

Phenylselanyl group incorporation for "glutathione peroxidase-like" activity modulation

The ability of organoselenium molecules to mimic the activity of the antioxidant selenoenzyme glutathione peroxidase (GPx) allows for their use as antioxidant or prooxidant modulators in several diseases associated with the disruption of the cell redox homeostasis. Current drug design in the field is partially based on specific modifications of the known Se-therapeutics aimed at achieving more selective bioactivity towards particular drug targets, accompanied by low toxicity as the therapeutic window for organoselenium compounds tends to be very narrow. Herein, we present a new group of Se-based antioxidants, structurally derived from the well-known group of GPx mimics-benzisoselenazol-3(2H)-ones. A series of N-substituted unsymmetrical phenylselenides with an o-amido function has been obtained by a newly developed procedure: a copper-catalyzed nucleophilic substitution by a Se-reagent formed in situ from diphenyl diselenide and sodium borohydride. All derivatives were tested as antioxidants and anticancer agents towards breast (MCF-7) and leukemia (HL-60) cancer cell lines. The highest H2O2-scavenging potential was observed for N-(3-methylbutyl)-2-(phenylselanyl)benzamide. The best antiproliferative activity was found for (-)-N-(1S,2R,4R)-menthyl-2-(phenylselanyl)benzamide (HL-60) and ((-)-N-(1S,2R,3S,6R)-(2-caranyl))benzamide (MCF-7). The structure-activity correlations, including the differences in reactivity of the obtained phenyl selenides and corresponding benzisoselenazol-3(2H)-ones, were performed.

PPh3/I2/HCOOH: An efficient CO source for the synthesis of phthalimides

A straightforward and general method has been developed for the synthesis of phthalimide derivatives from 2-iodobenzamides and PPh3/I2/HCOOH in the presence of a catalytic amount of Pd(OAc)2. The reaction results demonstrate that PPh3/I2/HCOOH is a facile, efficient and safe CO source. The whole process is carried out in toluene at 80 °C and furnishes the desired products in good to excellent yields.

Synthesis of dibenzodiazepinones via tandem copper(I)-catalyzed C-N bond formation

An efficient, one-pot method for the synthesis of dibenzodiazepinone derivatives involving copper-catalyzed tandem C-N bond formation is reported. The use of various halo amide and 2-iodoaniline derivatives permitted the synthesis of an array of dibenzodiazepinone derivatives in moderate to good yields. Moreover, a dibenzodiazepinone derivative {2-(11-oxo-5H-dibenzo[b,e][1, 4]diazepin-10(11H)-yl)benzonitrile} was utilized to synthesize the triazapentacyclic ring derivative {12-chloro- 8,15,22-triazapentacyclo[13.7.0. 02,7.09,14.016,21]docosa-1(22),2,4,6,9(14),10, 12,16(21),17,19-decaene}.

Direct arylation under catalysis of an oxime-derived palladacycle: Search for a phosphane-free method

A phosphane-free method for the direct arylation of benzothiazole by employing oxime-derived palladacycle 1 as a catalyst was developed. The new catalyst system can be used for 2-arylations by using aryl bromides and iodides. In addition, this method is especially suitable for the intramolecular direct coupling of bromo-and iodoamides, as well aschloroamides, to achieve a rapid synthesis of benzo[c]phenanthridine alkaloids. Direct arylation reactions under catalysis of an oxime-derived palladacycle were investigated. This phosphane-free method is applicable for the 2-arylation of benzothiazole and is especially suitable for the intramolecular direct coupling of bromo-and iodoamides, as well as chloroamides, to achieve rapid synthesis of benzo[c]phenanthridine alkaloids.

Synergistic effect of palladium and copper catalysts: Catalytic cyclizative dimerization of ortho-(1-alkynyl)benzamides leading to axially chiral 1,3-butadienes

Two is better than one: In the presence of Pd(OAc)2 and Cu(OAc)2, o-(1-alkynyl)benzamides 1 were converted into bis-iminobenzoisofurans with an axially chiral 1,3-diene 2 unit. The coexistence of both Pd and Cu catalysts was found to be essential for both the cyclizative dimerization process and for the observed unusual cyclization mode. Copyright

Palladium mediated synthesis of isoindolinones and isoquinolinones

The palladium-catalyzed reactions of 2-iodo-N-substituted benzamides 5-10 with acrylic esters 11-14 led to N-substituted-3-alkylisoindolinone esters 15-22 in good yields. The esters of isoindolinones 15-22 underwent hydrolysis reactions yielding the N-aryl-1,2,3,4-tetrahydro-1-oxoisoquinoline-3-carboxylic acid 26-31 in good yields.
