Butterfly-shaped structure, as a novel scaffold with an attractive and certain shape, have been widely used in new drug discovery. Tubulin, composing of α- and β-tubulin heterodimers, plays a key role in mitosis and cell division which are regarded as an excellent target for cancer therapy. Currently, a series of butterfly shape diaryl heterocyclic compounds have been reported with strong potential against tubulincolchicine binding site. It have one ring buried in the β subunit, another ring interacts with the α subunit and the main body is located in the flat pocket. Here, we firstly introduce the concept of butterfly structure for the tubulin inhibitors, focus on the latest progress on a variety of molecules bearing butterfly structure and also illuminate the challenges and future direction of butterfly structure-based tubulincolchicine binding site inhibitors.Monoclonal antibodies (mAbs) have always provided outstanding therapeutic arsenal in the treatment of cancer, be it hematological malignancies or solid tumors. Monoclonal antibodies mediated targeting of cancer genes in general and tumor-suppressor genes in particular have appreciably allowed the possibilities of trafficking these antibodies to specific tumor mechanisms and aim for the pin-pointly maneuvered tumor treatment strategies. The conventional cancer treatment options are associated with enormous limitations like drug resistance, acute and pan-toxic side effects and collateral damage to other unrelated cells and organs. Therefore monoclonal antibody mediated treatments have the special advantages of specific targeting of cancer related genes and minimizing the off-target side effects. Large number of monoclonal antibody mediated treatment regimen viz. use of immunoconjugates, clinically targeting TGFβ with pan-TGFβ monoclonal antibodies, p53 by its monoclonal antibodies and EGFR-targeted monoclonal a towards tumor suppressor genes in anti-cancer therapeutics.Background Chemoinformatics has several applications in the field of drug design, helping to identify new compounds against a range of ailments. Among these are Leishmaniasis, effective treatments for which are currently limited. Objective To construct new indole 2-aminothiophene molecules using computational tools and to test their effectiveness against Leishmania amazonensis (sp.). Methods Based on the chemical structure of thiophene-indol hybrids, we built regression models and performed molecular docking, and used these data as bases for design of 92 new molecules with predicted pIC50 and molecular docking. Among these, six compounds were selected for the synthesis and to perform biological assays (leishmanicidal activity and cytotoxicity). Results The prediction models and docking allowed inference of characteristics that could have positive influences on leishmanicidal activity of the planned compounds. Six compounds were synthesized, one-third of which showed promising antileishmanial activities, with IC50 ranging from 2.16 and 2.97 µM (against promastigote forms) and 0.9 and 1.71 µM (against amastigote forms), with selectivity indexes (SI) of 52 and 75. Conclusion These results demonstrate the ability of Quantitative Structure-Activity Relationship (QSAR)-based rational drug design to predict molecules with promising leishmanicidal potential, and confirming the potential of thiophene-indole hybrids as potential new leishmanial agents.Background Alzheimer's disease (AD), a neurological disorder, is the most common cause of senile dementia. Butyrylcholinesterase (BuChE) enzyme plays a vital role to regulatethe brain acetylcholine (ACh) neurotransmitter, but in the case of Alzheimer's disease (AD), BuChE activity gradually increases in patients with a decrease intheacetylcholine (ACh) concentration via hydrolysis. ACh plays an essential role in regulating learning and memory as the cortex originates from the basal forebrain, and thus, is involved in memory consolidation in these sites. Methods In this work, we have developed partial least squares (PLS)-regression based two dimensional quantitative structure-activity relationship (2D-QSAR) models using 1130 diverse chemical classes of compounds with defined activity against the BuChE enzyme. Keeping in mind the strict Organization for Economic Co-operation and Development (OECD) guidelines, we have tried to select significant descriptors from the large initial pool of descriptors using multi-oting the hydrogen bond interactions would be important for increasing the inhibitory activity against BuChE enzyme. Conclusion Furthermore, molecular docking studies have been carried out to understand the molecular interactions between the ligand and receptor, and the results are then correlated with the structural features obtained from the QSAR models. The information obtained from the QSAR models are well corroborated with the results of the docking study.Due to the increasing prevalence of cancer year by year, and the complexity and refractory nature of the disease itself, it is required to constantly innovate the development of new cancer treatment schemes. At the same time, the understanding of cancers has deepened, from the use of chemotherapy regimens with high toxicity and side effects, to the popularity of targeted drugs with specific targets, to precise treatments based on tumor characteristics rather than traditional anatomical location classification. In precision medical, in the view of the specific tumor diseases and their biological characteristics, it has great potential to develop tissue-agnostic targeted therapy with broad-spectrum anticancer significance. The present review has discussed tissue-agnostic targeted therapy based on the biological and genetic characteristics of cancers, expounded its theoretical basis and strategies for drug development. And the feasible drug targets, FDA-approved drugs, as well as drug candidates in clinical trials have also been summarized. In conclusion, the "tissue-agnostic targeted therapy" is a breakthrough in anticancer therapies.Background Biogenic amines are harmful to human health at a certain extent. As a kind of biogenic amine oxidase, multicopper oxidase can be used to degrade them. Currently, the literature about enzyme from Enterococcus spp. are limited, and recombinant multicopper oxidase might be an effective way to degrade biogenic amines. Objective (i) Select and identify strains that can degrade biogenic amines, (ii) overexpress enzyme from Enterococcus spp., (iii) measure gene expression and probe amine-degradation differences among strains (native, E. coli DH5α, and L. delbruckii), and (iv) examine the biochemical properties of recombinant multicopper oxidase, (v) apply the recombinant enzyme into smoked horsemeat sausage. Methods Reverse transcription PCR and high-performance liquid chromatography were performed to examine gene expression and amine degradation rate. Results The results demonstrated that target enzymes were successfully overexpressed, accompanied by increased aminedegrading activity (P less then 0.05). Gene from E. faecalis M5B was expressed in L. delbrueckii resulted in degradation rates for phenylethylamine, putrescine, histamine and tyramine of 54%, 52%, 70% and 40%, respectively, significantly higher than achieved by other recombinant strains. Conclusion In this work, gene expression levels were higher in recombinant M5B than recombinant M2B, regardless of host. E. coli is more stable to express multicopper oxidase. Besides, the amine-degrading ability was markedly increased in the two recombinant strains. After prolonged incubation, the recombinant enzyme could degrade three amines, and it displayed high alkali resistance and thermostability.Acromegaly and Growth Hormone (GHD) deficiency are associated with skeletal fragility and with an increased prevalence of vertebral fractures (VFs). In the most recent years, several authors tried to investigate surrogate markers that may predict the risk of bone fragility in these endocrine disorders. The aim of this review is to evaluate the role of GH receptor polymorphisms in skeletal fragility in patients affected by GHD and acromegaly. In fact, until now, two different isoforms of the GH Receptor (GHR) were described, that differ for the presence or the absence of transcription of the exon 3 of the GHR gene. Both the isoforms produce a functioning receptor, but the exon 3-deleted isoforms (d3-GHR) has a higher sensitivity to endogenous and recombinant GH as compared to the full-length isoform (fl-GHR).Context To identify VA and non-VA Emergency Department (ED) and hospital utilization by veterans with spinal cord injury and disorders (SCI/D) in California. Design Retrospective cohort study. Setting VA and Office of Statewide Health Planning and Development (OSHPD) in California. Participants Total 300 veterans admitted to the study VA SCI/D Center for initial rehabilitations from 01/01/1999 through 08/17/2014. Interventions N/A. Outcome Measures Individual-level ED visits and hospitalizations during the first-year post-rehabilitation. Results Among 145 veterans for whom ED visit data available, 168 ED visits were identified 94 (55.2%) at non-VA EDs and 74 (44.8%) at the VA ED, with a mean of 1.16 (±2.21) ED visit/person. Seventy-seven (53.1%) veterans did not visit any ED. Of 68 (46.9%) veterans with ≥ one ED visit, 20 (29.4%) visited the VA ED only, 34 (50.0%) visited non-VA EDs only, and 14 (20.6%) visited both VA and non-VA EDs. Among 212 Veterans for whom hospitalization data were available, 247 hospitalizations were identified 82 (33.2%) non-VA hospitalizations and 165 (66.8%) VA hospitalization with a mean of 1.17 (±1.62) hospitalizations/person. One hundred-seven (50.5%) veterans had no hospitalizations. Of 105 veterans with ≥ one hospitalization, 58 (55.2%) were hospitalized at the study VA hospital, 15 (14.3%) at a non-VA hospital, and 32 (30.5%) at both VA and non-VA hospitals. Conclusion Non-VA ED and hospital usage among veterans with SCI/D occurred frequently. The acquisition of non-VA healthcare data managed by state agencies is vital to accurately and comprehensively evaluate needs and utilization rates among veteran populations.Taiwan experienced two waves of imported infections with Coronavirus Disease 2019 (COVID-19). This study aimed at investigating the genomic variation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Taiwan and compared their evolutionary trajectories with the global strains. We performed culture and full-genome sequencing of SARS-CoV-2 strains followed by phylogenetic analysis. A 382-nucleotides deletion in open reading frame 8 (ORF8) was found in a Taiwanese strain isolated from a patient on February 4, 2020 who had a travel history to Wuhan. Patients in the first wave also included several sporadic, local transmission cases. Genomes of 5 strains sequenced from clustered infections were classified into a new clade with ORF1ab-V378I mutation, in addition to 3 dominant clades ORF8-L84S, ORF3a-G251V and S-D614G. check details This highlighted clade also included some strains isolated from patients who had a travel history to Turkey and Iran. The second wave mostly resulted from patients who had a travel history to Europe and Americas.
