Design, Synthesis, and Anticancer Activities of Benzofuran-Isatin Hybrids Tethered by Pentylene and Hexylene

Fourteen benzofuran-isatin hybrids 6a-f and 7a-h tethered via alkyl linker (pentylene and hexylene) were designed and synthesized, and hybrids 6c-f and 7a-h were screened for their in vitro anticancer activity against various human cancer cell lines. The majority of the hybrids were active against the tested cancer cells, and the most active hybrids 7g (half maximal inhibitory concentration/IC50: 77.2-88.9 mu M) and 7h (IC50: 65.4-89.7 mu M), which possessed broad spectrum anticancer activity were as potent as the reference vorinostat (IC50: 64.2->100 mu M) against all tested cancer cell lines, could act as leads for further investigations. The structure-activity relationship is also discussed, and the enriched structure-activity relationship may afford useful information for further rational design of the candidates with higher activity.

Exploring the Multi-Target Neuroprotective Chemical Space of Benzofuran Scaffolds: A New Strategy in Drug Development for Alzheimer’s Disease

Alzheimer’s disease (AD) is an irreversible and progressive neurodegenerative disorder that slowly destroys memory. The precise mechanism of AD is still not entirely understood and remains under discussion; it is believed to be a multifactorial disease in which a number of mechanisms are involved in its pathogenesis. Worldwide, near 37 million people suffer from the effects of AD. As a cause of death for elderly, it is predicted that AD will rank third in the coming years, just behind cancer and heart disease. Unfortunately, AD remains an incurable condition. Despite the devastating problems associated with AD, there are only four FDA approved drugs for palliative treatment of this pathology. Hence, renewed scientific efforts are required not only to uncover more insights into the AD process but also to develop more efficient pharmacological tools against this disease. Due to the complexity and multiple mechanisms at play in the progression of AD, the development of drugs by rational design is extremely difficult. The existing drugs to fight against Alzheimer’s have had limited success, mainly due to their ability to modulate only one of the mechanisms involved in AD. As opposed to single-targeted strategies, the identification of small molecules able to affect multiple pathways involved in Alzheimer’s is a promising strategy to develop more efficient medicines against this disease. Central to existing efforts to develop pharmaceuticals controlling AD is the discovery of new chemicals displaying strong neuroactivity. Benzofurans are privileged oxygen containing heterocycles that have a strong neuroprotective behavior, inhibiting several of the important events involved in the AD process. In this review, an approach is presented that relies on expanding the neuroprotective chemical space of benzofuran scaffolds by accessing them from Andean-Patagonian fungi and synthetic sources (chemical libraries). The exploration of the neuroprotective chemical space of these scaffolds has the potential to allow the discovery of substitution patterns that display multi-target neuroactivity against multiple events involved in AD. This benzofuran chemical framework will establish a multi-target chemical space that could set the basis for the development of super drugs against AD.

N-Benzyl Derivatives of Long-Chained 4-Amino-7-chloro-quionolines as Inhibitors of Pyocyanin Production in Pseudomonas aeruginosa

Pseudomonas aeruginosa is a leading cause of nosocomial infections that are becoming increasingly difficult to treat due to the occurrence of antibiotic resistant strains. Since P. aeruginosa virulence is controlled through quorum sensing, small molecule treatments inhibiting quorum sensing signaling pathways provide a promising therapeutic option. Consequently, we synthesized a series of N-octaneamino-4-aminoquinoline derivatives to optimize this chemotype’s antivirulence activity against P. aeruginosa via inhibition of pyocyanin production. The most potent derivative, which possesses a benzofuran substituent, provided effective inhibition of pyocyanin production (IC50 = 12 mu M), biofilm formation (BFIC50 = 50 mu M), and motility. Experimentally, the compound’s activity is achieved through competitive inhibition of PqsR, and structure-activity data were rationalized using molecular docking studies.

Synthesis and evaluation of novel two-photon fluorescence probes for in vivo imaging of amylin aggregates in the pancreas

The deposition of islet amyloid consisting of amylin aggregates is one of the hallmarks of type 2 diabetes mellitus (T2DM). Therefore, the amylin aggregate is regarded as an attractive target for diagnosis, treatment and elucidation of the pathogenic mechanism of T2DM. However, no fluorescence probe for in vivo imaging of amylin aggregates has been reported. In this study, we evaluated four fluorescent probes (DANIRs) including two novel compounds (DANIR-OH 2b and DANIR-OH 2c) for two-photon fluorescence imaging of amylin aggregates in the pancreas. All DANIFts showed binding affinity for amylin aggregates and clearly stained amylin aggregates in pancreatic sections of the islet amylin model mice and T2DM patients in in viwo. In an ex vivo fluorescence staining study, these probes also bound to amylin aggregates in the pancreas of the islet amylin model mice. Furthermore, in an in vivo two-photon fluorescence imaging study, we clearly imaged the amylin aggregates after injecting DANIFts via the tail vein of the islet amyloid model mice. The results suggest that DANIRs may be useful for two-photon fluorescence imaging of amylin aggregates in the living mouse pancreas.

Inuloxin E, a New Seco-Eudesmanolide Isolated from Dittrichia viscosa, Stimulating Orobanche cumana Seed Germination

A new sesquiterpenoid belonging to the subgroup seco-eudesmanolides and named inuloxin E was isolated from Dittrichia viscosa, together with the already known sesquiterpenoids inuloxins A-D and alpha -costic acid. Inuloxin E was characterized by spectroscopic data (essentially NMR and ESI MS) as 3-methylene-6-(1-methyl-4-oxo-pentyl)-3a,4,7,7a-tetrahydro-3H-benzofuran-2-one. Its relative configuration was determined by comparison with the closely related inuloxin D and chemical conversion of inuloxin E into inuloxin D and by the observed significant correlation in the NOESY spectrum. Both inuloxins D and E induced germination of the parasitic weed Orobanche cumana, but were inactive on the seeds of Orobanche minor and Phelipanche ramosa. The germination activity of some hemisynthetic esters of inuloxin D was also investigated.

Structural optimization, molecular docking analysis, electronic and vibrational properties have been investigated for the 1-benzofuran-2-carboxylic acid (2BF) and 1-benzofuran-3-carboxylic acid (3BF) using DFT/ B3LYP/6-311 + + G(d,p) level of theory. The theoretical parameters have a very good consistency with the experimental ones. The weak intermolecular interactions were analyzed by different tool such as: Hirshfeld surfaces, topological analysis and natural bond orbital studies. The nonlinear optical properties have been investigated. Molecular electrostatic potential and frontier molecular orbitals (FM0s) analysis have been carried out to understand the reactivity of the molecule. In addition, TD-DFT calculation is initiated to simulate the UV-vis absorption spectrum and to determine several important electronic properties like HOMO-LUMO gap energy and electronic transitions. The complete vibrational assignments and the force constants were reported for monomer and dimers of both acids. The biological activities of the tow acids have been studied via molecular docking analysis. The later calculations prove that the studied acids have an inhibitor effect against cancer and microbial diseases.

Multidirectional in vitro and in cellulo studies as a tool for identification of multi-target-directed ligands aiming at symptoms and causes of Alzheimer’s disease

Effective therapy of Alzheimer’s disease (AD) requires treatment with a combination of drugs that modulate various pathomechanisms contributing to the disease. In our research, we have focused on the development of multi-target-directed ligands – 5-HT6 receptor antagonists and cholinesterase inhibitors – with disease-modifying properties. We have performed extended in vitro (FRET assay) and in cellulo (Escherichia coli model of protein aggregation) studies on their beta-secretase, tau, and amyloid beta aggregation inhibitory activity. Within these multifunctional ligands, we have identified compound 17 with inhibitory potency against tau and amyloid beta aggregation in in cellulo assay of 59% and 56% at 10 mu M, respectively, hBACE IC50=4 mu M, h5TH6 K (i)=94 nM, hAChE IC50=26 nM, and eqBuChE IC50=5 nM. This study led to the development of multifunctional ligands with a broad range of biological activities crucial not only for the symptomatic but also for the disease-modifying treatment of AD.
