Directed Evolution of P450 BM3 towards Functionalization of Aromatic O-Heterocycles

The O-heterocycles, benzo-1,4-dioxane, phthalan, isochroman, 2,3-dihydrobenzofuran, benzofuran, and dibenzofuran are important building blocks with considerable medical application for the production of pharmaceuticals. Cytochrome P450 monooxygenase (P450) Bacillus megaterium 3 (BM3) wild type (WT) from Bacillus megaterium has low to no conversion of the six O-heterocycles. Screening of in-house libraries for active variants yielded P450 BM3 CM1 (R255P/P329H), which was subjected to directed evolution and site saturation mutagenesis of four positions. The latter led to the identification of position R255, which when introduced in the P450 BM3 WT, outperformed all other variants. The initial oxidation rate of nicotinamide adenine dinucleotide phosphate (NADPH) consumption increased approximate to 140-fold (WT: 8.3 +/- 1.3 min(-1); R255L: 1168 +/- 163 min(-1)), total turnover number (TTN) increased approximate to 21-fold (WT: 40 +/- 3; R255L: 860 +/- 15), and coupling efficiency, approximate to 2.9-fold (WT: 8.8 +/- 0.1%; R255L: 25.7 +/- 1.0%). Computational analysis showed that substitution R255L (distant from the heme-cofactor) does not have the salt bridge formed with D217 in WT, which introduces flexibility into the I-helix and leads to a heme rearrangement allowing for efficient hydroxylation.

Synthesis of sigma Receptor Ligands with a Spirocyclic System Connected with a Tetrahydroisoquinoline Moiety via Different Linkers

With the aim to develop new sigma(2) receptor ligands, spirocyclic piperidines or cyclohexanamines with 2-benzopyran and 2-benzofuran scaffolds were connected to the 6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline moiety by variable linkers. In addition to flexible alkyl chains, linkers containing an amide as functional group were synthesized. The 2-benzopyran and 2-benzofuran scaffold of the spirocyclic compounds were synthesized from 2-bromobenzaldehyde. The amide linkers were constructed by acylation of amines with chloroacetyl chloride and subsequent nucleophilic substitution, the alkyl linkers were obtained by LiAlH4 reduction of the corresponding amides. For the development of sigma(2) receptor ligands, the spirocyclic 2-benzopyran scaffold is more favorable than the ring-contracted 2-benzofuran system. Compounds bearing an alkyl chain as linker generally show higher sigma affinity than acyl linkers containing an amide as functional group. A higher sigma(1) affinity for the cis-configured cyclohexanamines than for the trans-configured derivatives was found. The highest sigma(2) affinity was observed for cis-configured spiro[[2]benzopyran-1,1 ‘-cyclohexan]-4 ‘-amine connected to the tetrahydroisoquinoline system by an ethylene spacer (cis-31, K-i (sigma(2))=200 nM; the highest sigma(1) affinity was recorded for the corresponding 2-benzofuran derivative with a CH2C=O linker (cis-29, K-i (sigma(1))=129 nM).

Design, Synthesis and Antifungal Activity of Benzofuran and Its Analogues

The Summary of main observation and conclusion Benzofuran has antifungal activity as the inhibitor of N-myristoyltransferase. Twenty-nine novel benzofuran-semicarbazide hybrids were designed and synthesized by principle of drug combinationatory. On this basis, the benzofuran ring was simplified to a resorcinol structure, and sixteen novel 1,3-dialkoxybenzene-semicarbazide hybrids were designed and synthesized. All structures of the target compounds were characterized by HRMS and NMR. The in vitro antifungal activity of target compounds was evaluated using the microdilution broth method against eight strains of pathogenic fungi with fluconazole as positive control. According to the results of the target compounds, structure-activity relationship (SAR) is summarized. The inhibitory activity against the tested strains of simplified compounds (K01-K16) has different levels improvement compared with compounds Z01-Z29. K01-K16 showed significant antifungal activities against A. fumigatus, C. kruseii, and sensitive C. albicans 5314. Notably, compounds Z20, Z22, K10, K11 and K16 also displayed different activities against two fluconazole-resistance strains that were isolated from AIDS patients. The minimal inhibitory concentration (MIC) values against fluconazole-resistant strains were in the range of 2-8 mu g/mL and 4-32 mu g/mL, respectively. Furthermore, molecular docking was performed to investigate the binding affinities and interaction modes between the target compound and N-myristoyltransferase.

Multi-step parallel synthesis enabled optimization of benzofuran derivatives as pan-genotypic non-nucleoside inhibitors of HCV NS5B

In a lead optimization effort towards NS5B NNI inhibitors, two multi-step parallel libraries were designed and successfully synthesized. Through this effort we discovered compound 9B, which achieved rigorous and delicate balance of inhibition across the common genotypes and mutants with < 10 nM potency. In addition, the bicyclic compounds 9B exhibited improved FASSIF solubility over the tetracyclic compound MK-8876. This strategic approach demonstrated that, even within limited reaction scope, multi-step parallel libraries could provide access to more complex chemical space. This expedient access facilitates diverse, purpose-driven optimization of SAR and physicochemical properties.

Preclinical Evaluation of Amphihevir, a First-in-Class Clinical Hepatitis C Virus NS4B Inhibitor

Amphihevir, a benzofuran derivative, is the first reported hepatitis C virus (HCV) nonstructural protein 4B (NS4B) inhibitor that has advanced to clinical trials (currently in phase 1b trial [CTR20170632]). Here, we report the results of a preclinical study of its potency, toxicity, selectivity, drug metabolism and pharmacokinetics (DMPK), and safety profiles. Amphihevir displayed good antiviral activities against genotype 1a (50% effective concentration [EC50) of 0.34 nM) and genotype 1b (EC50 of 1.97 nM) replicons and no cytotoxicity in 12 cell lines derived from animals and humans. Amphihevir was found to be inactive against other viruses, human kinases, and G protein-coupled receptors (GPCRs), which implies its good selectivity. A 9-day long-term treatment of genotype 1b replicons with amphihevir resulted in a 3.8 Log(10) decline of the hepatitis C viral RNA at a concentration of 25x EC50. Drug resistance screening showed that mutations occurred at H94, F98, and V105 of NS4B, which mediated the resistance to amphihevir. This result suggests that NS4B is the main target of amphihevir. There was no cross-resistance between amphihevir and NS5A, NS3/4A, and NS5B inhibitors, suggesting that amphihevir in combination with other anti-hepatitis C virus drugs could be used to treat hepatitis C, as proven by studies of amphihevir and other hepatitis C virus inhibitors. Pharmacokinetic studies demonstrated that amphihevir has good oral bioavailability and appropriate half-life (t(1/2)) in rats and dogs, thereby supporting its use once per day. Finally, amphihevir showed good safety profiles in rats and dogs. The results shed light on the use of amphihevir as a potential treatment option for chronic hepatitis C patients.

A Comparative Study of the Anticancer Activity and PARP-1 Inhibiting Effect of Benzofuran-Pyrazole Scaffold and Its Nano-Sized Particles in Human Breast Cancer Cells

Breast cancer is considered the most common and deadly cancer among women worldwide. Nanomedicine has become extremely attractive in the field of cancer treatment. Due to the high surface to volume ratio and other unique properties, nanomaterials can be specifically targeted to certain cells and tissues to interact with the living systems. The strategic planning of this study is based on using the nanoprecipitation method to prepare nanoparticles BZP-NPs (3.8-5.7 nm) of the previously prepared benzofuran-pyrazole compound (IV) BZP which showed promising cytotoxic activity. The capacity of BZP and BZP-NPs to suppress the growth of human breast tumor MCF-7 and MDA-MB-231 cells was evaluated using MTT assay. The IC50 doses of BZP and BZP-NPs targeting normal breast cells MCF-12A exceeded those targeting the cancer cells by >1000-fold, demonstrating their reasonable safety profiles in normal cells. Furthermore, cell cycle analysis, apoptosis induction detection, assessment of p53, Bcl-2, caspase-3, and PARP-1 levels of BZP and its nano-sized-BZP-NPs particles were also evaluated. Although the obtained results were in the favor of compound IV in its normal-sized particles, BZP-NPs appeared as a hit compound which showed improved cytotoxicity against the tested human breast cancer cells associated with the induction of pre-G1 apoptosis as well as cell cycle arrest at G2/M phase. The increase in caspase-3 level, upregulation of p53, and downregulation of Bcl-2 protein expression levels confirmed apoptosis. Furthermore, ELISA results exhibited that BZP-NPs produced a more favorable impact as a PARP-1 enzyme inhibitor than the parent BZP.

Spiroindolone analogues bearing benzofuran moiety as a selective cyclooxygenase COX-1 with TNF-alpha and IL-6 inhibitors

To design and discover a new compound can used as a COX with TNF-alpha and IL-6 inhibitors is highly challenge. A series of spiroindolone-bearing benzofuran moieties were resynthesized from the chalcone-based benzo[b]furan with substituted isatin, and amino acids. The requisite spiroindolone analogues were tested for their potential inhibitory activities against lipid metabolizing enzymes such as cyclooxygenase COX-1, COX-2, and the release of pro-inflammatory cytokines interleukin IL-6, and tumor necrosis factor TNF-a. Among the tested compounds, 5a, 5c, 5h, 5i, 5l, and 5p exhibited COX-1 inhibitor selectively with percent of inhibition 40.81-83.4% and IC50 values ranging from 20.42 mu M to 38.24 mM. In addition, all the synthesized target compounds possessed lipopolysaccharide-induced TNF-alpha, and IL-6 expression with a varying degree of COX-1 inhibition. Compounds 5d, 5e, 5f, 5g, and 5k markedly inhibited TNF-alpha, and IL-6 release in WI-38 fibroblast cells. Molecular docking of the most effective and highly selective compounds were investigated and shown important binding mechanisms which could affect pro-inflammatory enzymes and cytokines via the inhibition of COX-1, COX-2, IL-6, and TNF-alpha.
