A Virtual Screening algorithm has to adapt to the different stages of this process. Early screening needs to ensure that all bioactive compounds are ranked in the first positions despite of the number of false positives, while a second screening round is aimed at increasing the prediction accuracy.

A novel CNN architecture is presented to this aim, which predicts bioactivity of candidate compounds on CDK1 using a combination of molecular fingerprints as their vector representation, and has been trained suitably to achieve good results as regards both enrichment factor and accuracy in different screening modes (98.55% accuracy in active-only selection, and 98.88% in high precision discrimination).

The proposed architecture outperforms state-of-the-art ML approaches, and some interesting insights on molecular fingerprints are devised.

In [Prezza et al., AMB 2019], a new reference-free and alignment-free framework for the detection of SNPs was suggested and tested. EI1 , based on the Burrows-Wheeler Transform (BWT), significantly improves sensitivity and precision of previous de Bruijn graphs based tools by overcoming several of their limitations, namely (i) the need to establish a fixed value, usually small, for the order k, (ii) the loss of important information such as k-mer coverage and adjacency of k-mers within the same read, and (iii) bad performance in repeated regions longer than k bases. The preliminary tool, however, was able to identify only SNPs and it was too slow and memory consuming due to the use of additional heavy data structures (namely, the Suffix and LCP arrays), besides the BWT.

In this paper, we introduce a new algorithm and the corresponding tool ebwt2InDel that (i) extend the framework of [Prezza et al., AMB 2019] to detect also INDELs, and (ii) implements recent algorithmic findings that allow to perffind up to 83% of the SNPs and 72% of the existing INDELs. These percentages considerably improve the 71% of SNPs and 51% of INDELs found by the state-of-the art tool based on de Bruijn graphs. We furthermore report results on larger (real) Human whole-genome sequencing experiments. Also in these cases, our tool exhibits a much higher sensitivity than the state-of-the art tool.Since the elucidation of the leaching process by Mizoroki in the 1970s, the research focused on this problem has increased. #link# As a result, it has been discovered that the leached metals can not only hinder product yield, but they can also remain as contaminants of the final products. Thus, it can be concluded that metal leaching needs to be diminished or avoided more efficiently. This problem is important for industry and the environment because of the increases in costs and pollution. In 2014 we reported a brief review related to this important feature; now we would like to report on the latest findings on this important phenomenon, including an update on the mechanisms used to explain leaching and the reactions that support those mechanisms and including patents related to leaching in catalysis that have appeared in recent years.Neurodegenerative diseases including Alzheimer's, Parkinson's and Huntington disease are have serious concern due to its effect on the quality of life of affected persons. Neurodegenerative diseases have some limitations for both diagnostic as well as at treatment level. Introducing nanotechnology, for the treatment of these diseases may contribute significantly in solving the problem. There are several treatment strategies for the neurodegenerative diseases, but their limitations are the entry into the due to the presence of the blood-brain barrier (BBB). The present review highlights the application of nanotechnology during last 20 years for the treatment of neurodegenerative diseases.
Body defenses and metabolic processes probably co-evolved in such a way that rapid, energyintensive acute inflammatory repair is functionally integrated with energy allocation in a starvation/ infection / injury-prone primitive environment. Disruptive metabolic surplus, aggravated by sedentary lifestyle, induces chronic under-activation of AMPK, the master regulator of intracellular energy homeostasis. Sudden increase in chronic, dysregulated 'sterile' inflammatory disorders probably results from a shift towards calorie rich, sanitized, cushioned, injury/ infection free environment, repositioning inflammatory repair pathways towards chronic, non-microbial, 'sterile', 'low grade', 'parainflammation'. AMPK, (at the helm of energy provisioning) supervises the metabolic regulation of inflammasome activation, a common denominator in lifestyle disorders.

In this review we discuss various pathways linking AMPK under-activation and inflammasome activation. AMPK under-activation, the possible norm in energy-rich sedentary lifestyle, could be the central agency that stimulates inflammasome activation by multiple pathways such as [1] decreasing autophagy, and accumulation of intracellular DAMPs, (particulate crystalline molecules, advanced glycation end-products, oxidized lipids etc.) [2] stimulating a glycolytic shift (pro-inflammatory) in metabolism, [3] promoting NF-kB activation and decreasing Nrf2 activation, [4] increasing reactive oxygen species (ROS) formation, unfolded protein response( UPR) and endoplasmic reticulum (ER) stress.

The 'inverse energy crisis', associated with calorie-rich, sedentary lifestyle, advocates dietary and pharmacological interventions for treating chronic metabolic disorders by overcoming / reversing AMPK under-activation.

Myeloid cell leukemia-1 (Mcl-1) protein, as a critical pro-survival member of the B-cell lymphoma 2 (Bcl-2) protein family, plays an important role in apoptosis, carcinogenesis and resistance to chemotherapies. Hence, potently and selectively inhibiting Mcl-1 to induce apoptosis has become a widely accepted anticancer strategy.

This review intends to provide a comprehensive overview of patents and primary literature, published from 2017 to present, on small molecule Mcl-1 inhibitors with various scaffolds. By analyzing the modes of compound-protein interactions, the similarities and differences of those structures are discussed, which could provide guidance for future drug design.

The primary accesses for patent searching are SciFinder and Espacenet®. Besides the data disclosed in patents, some results published in the follow-up research papers will be included in this review.

The review covers dozens of patents on Mcl-1 inhibitors in the past three years, and the scaffolds of compounds are mainly divided into indole scaffolds and non-indole scaffolds. The compounds described here are compared with the relevant inhibitors disclosed in previous patents, and representative compounds, especially those launched in clinical trials, are emphasized in this review.

For most of the compounds in these patents, analyses of the binding affinity to Mcl-1 and studies in multiple cell lines were conducted, wherein some compounds were tested in preclinical cancer models or were included in other biological studies. Some compounds showed promising results and potential for further study.

In material chemistry, the role of peptides in liquid crystals (LCs) is profound, especially in the rapid construction of supramolecular hierarchical networks. The importance of LCs for a variety of societal needs leads to the synthesis of innumerable LCs by conventional mesogenic strategy and non-conventional molecular design principles. For example, electronic appliances, including flat panel TV displays, electronic notebooks, digital cameras, domestic devices, use LCs as an integral component for such applications. Also, LCs are useful in biological systems including stem cell research, sensors for bacteria, virus, and proteins. These accomplishments are possible mostly due to the non-conventional molecular design principles for crafting LCs using smaller molecular mancements.By combining Machine Learning (ML) methods with Perturbation Theory (PT), it is possible to develop predictive models for a variety of response targets. Such combination often known as Perturbation Theory Machine Learning (PTML) modeling comprises a set of techniques that can handle various physical, and chemical properties of different organisms, complex biological or material systems under multiple input conditions. In so doing, these techniques effectively integrate a manifold of diverse chemical and biological data into a single computational framework that can then be applied for screening lead chemicals as well as to find clues for improving the targeted response(s). link2 PTML models have thus been extremely helpful in drug or material design efforts and found to be predictive and applicable across a broad space of systems. link3 After a brief outline of the applied methodology, this work reviews the different uses of PTML in Medicinal Chemistry, as well as in other applications. Finally, we cover the development of software available nowadays for setting up PTML models from large datasets.Alzheimer's Disease (AD) is a devastating neurodegenerative disease that affects millions of people in the world. The abnormal aggregation of amyloid β protein (Aβ) is regarded as the key event in AD onset. Meanwhile, the Aβ oligomers are believed to be the most toxic species of Aβ. Recent studies show that the Aβ dimers, which are the smallest form of Aβ oligomers, also have the neurotoxicity in the absence of other oligomers in physiological conditions. In this review, we focus on the pathogenesis, structure and potential therapeutic molecules against small Aβ oligomers, as well as the nanoparticles (NPs) in the treatment of AD. In this review, we firstly focus on the pathogenic mechanism of Aβ oligomers, especially the Aβ dimers. The toxicity of Aβ dimer or oligomers, which attributes to the interactions with various receptors and the disruption of membrane or intracellular environments, were introduced. Then the structure properties of Aβ dimers and oligomers are summarized. Although some structural information such as the secondary structure content is characterized by experimental technologies, detailed structures are still absent. Following that, the small molecules targeting Aβ dimers or oligomers are collected; nevertheless, all of these ligands have failed to come into the market due to the rising controversy of the Aβ-related "amyloid cascade hypothesis". At last, the recent progress about the nanoparticles as the potential drugs or the drug delivery for the Aβ oligomers are present.
