A pyrrolo[1,2-a]pyrazine-based chemical territory was expanded via construction of new chemical library with distinctive substitution patterns, which was made possible by regiodivergent electrophilic acylation followed by aldol condensation. Biological screening of the compounds in this class revealed that the viability of human lymphoma U937 cells was strongly inhibited by 6b with a methoxy group at the o-position of the aromatic ring, but not by compounds 6t-w bearing a halogen at the o-position. Furthermore, 6x having a 2,4-dimethoxyphenyl group inhibited the survival of U937 cells more potently than 6b. In contrast, 6y possessing a 2,5-dimethoxyphenyl moiety did not show effective inhibition, implying the importance of orientation of the substituent(s) around the benzene ring. The anticancer action of 6x with safe therapeutic window could be associated with the FTase-p38 signaling axis.

The novel coronavirus disease COVID-19 that emerged in 2019 is caused by the virus SARS CoV-2 and named for its close genetic similarity to SARS CoV-1 that caused severe acute respiratory syndrome (SARS) in 2002. Both SARS coronavirus genomes encode two overlapping large polyproteins, which are cleaved at specific sites by a 3C-like cysteine protease (3CL(pro)) in a post-translational processing step that is critical for coronavirus replication. The 3CL(pro) sequences for CoV-1 and CoV-2 viruses are 100% identical in the catalytic domain that carries out protein cleavage. A research effort that focused on the discovery of reversible and irreversible ketone-based inhibitors of SARS CoV-1 3CL(pro) employing ligand-protease structures solved by X-ray crystallography led to the identification of 3 and 4. Preclinical experiments reveal 4 (PF-00835231) as a potent inhibitor of CoV-2 3CL(pro) with suitable pharmaceutical properties to warrant further development as an intravenous treatment for COVID-19.

Three-component reaction of methyl 4-aryl-2,4-dioxobutanoates with aromatic aldehyde and 2-aminoacetonitrile sulfate in glacial acetic acid in the presence of anhydrous sodium acetate afforded previously unknown (3-aroyl-2-aryl-4-hydroxy-5-oxo-2,5-dihydro-1H-pyrrol-1-yl)acetonitriles. The reaction involved intermediate formation of Schiff base, followed by Michael-type addition of the dioxo ester to the C=N bond and cyclization of the addition product, methyl 3-aroyl-4-aryl-4-(cyanomethylamino)-2-oxobutanoate. The cyclization product reacted with hydrazine hydrate at the aroyl carbonyl group to give the corresponding hydrazone which was converted in 1,4-dioxane to the cyclic form, [3,4-diaryl-6a-hydroxy-6-oxo-3a,4,6,6a-tetrahydropyrrolo[3,4-c]pyrazol-5(1H)-yl]acetonitrile, without elimination of the second water molecule. When the reaction of (3-aroyl-2-aryl-4-hydroxy-5-oxo-2,5-dihydro-1H-pyrrol-1-yl)acetomtriles with hydrazine hydrate was carried out in boiling acetic acid, [3,4-diaryl-6-oxo-2,6-dihydropyrrolo[3,4-c]pyrazol-5(4H)-yl]acetonitriles were obtained as a result of dehydration of initially formed [3,4-diaryl-6a-hydroxy-6-oxo-3a,4,6,6a-tetrahydropyrrolo[3,4-c]pyrazol-5(1H)-yl]acetonitriles as shown by special experiment. The structures of [6a-hydroxy-6-oxo-3,4-diphenyl-3a,4,6,6a-tetrahydropyrrolo[3,4-c]pyrazol-5(1H)-yl]acetonitrile and [4-(4-methoxyphenyl)-6-oxo-3-phenyl-2,6-dihydropyrrolo[3,4-c]pyrazol-5(4H)-yl]acetonitrile were determined by X-ray analysis.

Stable phenoxyl radicals H-bonded to phenols were successfully isolated. The effect of the intermolecular Hbonding to the concerted proton coupled electron transfer (CPET) reactions of the aldimines and the stability and spin distribution of the H-bonded phenoxyls are reported. Salts of iminium-phenol derivatives as cations and the corresponding imine-phenolato derivatives coordinated to zinc(II) as anions, [Zn-II((ArO)-O-R)Cl-2](-)[(ArOH2)-O-R](+), were isolated, where ArOH are aldimine derivatives. Notably, [Zn-II((ArO)-O-R)Cl-2](-)[(ArOH2)-O-R](+) salts undergo CPET reactions in air affording phenoxyl analogues, [Zn-II(ArOH)Cl-2]center dot ArO center dot center dot CH3CN. [Zn-II((ArO)-O-R)Cl-2](-)[(ArOH2)-O-R](+) salts incorporate intermolecular iminium-phenolato, [(Zn)Ar-O–+HN=CH-] H-bonds, while [Zn-II(ArOH)Cl-2]center dot ArO center dot center dot CH3CN moieties contain intermolecular phenoxyl-phenol, [Ar-O-HO-Ar](center dot), H-bonds. The phenoxyls are presented in two forms, [(Zn)Ar-O-center dot—HO-Ar (zinc phenoxyl) <-> (Zn)Ar-OH—O-center dot-Ar (free phenoxyl)]. In crystals, the spin density scatters on both phenolic fragments corresponding to a delocalized state, while in solution the latter form has been calculated as a ground electronic state. The X-band EPR spectra of crystals, solutions and frozen glasses were analyzed. The powder spectra at g = 2.0030 +/- 0.0005 and the frozen glass spectra at g = 2.0075 +/- 0.0003 follow the hyperfine patterns due to N-14 (I = 1) nuclei. In fluid solutions, the g values of the hyperfine signals due to (14) N and H-1 nuclei are 2.0078 +/- 0.0001. 1-3 exhibit absorption bands at 350-390 nm due to pi ->pi* intraligand charge transfer (ILCT) transitions, while the radical species, in addition to pi ->pi transitions at 405-440 nm, display phenol to phenoxyl intervalence charge transfer (WCT) transitions at 600-650 nm. The cyclic voltammograms (CVs) of 1-3 depend on the scan rates; at lower scan rates (100-400 mV/s) the CPET reactions occur at -0.92 to -0.96 V versus Fc(+)/Fc couple, whereas at higher scan rates (1000-2400 mV/s), the oxidation occurs by the electron transfer (ET) path at 0.05-0.12 V. Thus, a potential shift of similar to 1.0 V is recorded due to CPET reactions facilitated by H-bonding.

Up to 45 % of deaths in developed nations can be attributed to chronic fibroproliferative diseases, highlighting the need for effective therapies. The RGD (Arg-Gly-Asp) integrin alpha v beta 1 was recently investigated for its role in fibrotic disease, and thus warrants therapeutic targeting. Herein we describe the identification of non-RGD hit small-molecule alpha v beta 1 inhibitors. We show that alpha v beta 1 activity is embedded in a range of published alpha 4 beta 1 (VLA-4) ligands; we also demonstrate how a non-RGD integrin inhibitor (of alpha 4 beta 1 in this case) was converted into a potent non-zwitterionic RGD integrin inhibitor (of alpha v beta 1 in this case). We designed urea ligands with excellent selectivity over alpha 4 beta 1 and the other alpha v integrins (alpha v beta 3, alpha v beta 5, alpha v beta 6, alpha v beta 8). In silico docking models and density functional theory (DFT) calculations aided the discovery of the lead urea series.

Some novel N5-sulfonylated 4 were synthesized via sulfonylation of 5-amino-1H-pyrazole derivative 1 with arylsulfonyl chlorides. On the other hand, N1-alkylated pyrazoles 7 and 10 were synthesized through alkylation of compound 1 with each of chloroacetamides and ethylchloroacetate under different conditions. Condensation of compounds 4 and 7 with different aromatic aldehydes furnished the corresponding arylidene derivatives. In spite of, condensation of 10 with aromatic aldehydes afforded the 2-(5-amino-2-aryl-1H-pyrazol-1-yl)acetic acid. The structure of the newly synthesized compounds was elucidated by elemental analyses and spectral data. Also, the suggested mechanisms for their formation were studied. Additionally, some selected new compounds were screened against antimicrobial activity. Compound 7c exhibited a higher activity against Candida albicans (inhibition zone diameter [IZD] = 31.3 +/- 0.6 mm) than the standard antibiotic Nystatin (IZD = 21 +/- 0.5 mm). Also, compound 7c showed minimum inhibitory concentration = 125 and 250 mu g/mL against Klebsiella pneumonia and Staphylococcus aureus, respectively. Molecular docking study also was carried out for compound 7c.
