Different tail enigneered resorcinarenes have been examined towards the insulin fibrillation via experimental and computational studies. The resorcinarene showed a promising effect on the inhibition of insulin fibrillalition via ThT assay, CD spectra, and AFM images. Both ThT assay and computational results indicate the tail from the resorcinarene has an impact on insulin fibrillation by either inhibition or promotion because of the resident position on insulin. These observations have significant biological implications in the design of lead drug molecules as well as the development of potential therapeutic strategies...

Liposomes have become increasingly common in the delivery of bioactive agents due to their ability to encapsulate hydrophobic and hydrophilic drugs with excellent biocompatibility. While commercial liposome formulations improve bioavailability of otherwise quickly eliminated or insoluble drugs, tailoring formulation properties for specific uses has become a focus of liposome research. Here, we report the design, synthesis, and characterization of two series of amphiphilic macromolecules (AMs), consisting of acylated polyol backbones conjugated to poly(ethylene glycol) (PEG) that can serve as the sole additives to stabilize and control hydrophilic molecule release rates from distearoyl-phosphatidylcholine- (DSPC-) based liposomes...

Docetaxel, cisplatin plus fluorouracil (DCF) regimen is a useful chemotherapy, but is sometimes withdrawn due to severe adverse effects (AE). In this study, we examined whether the chronotherapy of DCF regimen could reduce the drugs-induced toxicities in clinical practice. Patients with oral squamous cell carcinoma were enrolled. Chemotherapy started at 10:30 (Morning-dosing) or 18:30 (Evening-dosing) for 5 days by a cross-over design. AE were assessed for 14 days after an initiation of each dosing. The grades of nausea, vomiting and neutropenia were smaller during Evening-dosing than during Morning-dosing...

Chemical modifications of human ribosomal RNA (rRNA) are introduced during biogenesis and have been implicated in the dysregulation of protein synthesis, as is found in cancer and other diseases. However, their role in this phenomenon is unknown. Here we visualize more than 130 individual rRNA modifications in the three-dimensional structure of the human ribosome, explaining their structural and functional roles. In addition to a small number of universally conserved sites, we identify many eukaryote- or human-specific modifications and unique sites that form an extended shell in comparison to bacterial ribosomes, and which stabilize the RNA...

The identification of chemical structures in natural product mixtures is an important task in drug discovery but is still a challenging problem, as structural elucidation is a time-consuming process and is limited by the available mass spectra of known natural products. Computer-aided structure elucidation (CASE) strategies seek to automatically propose a list of possible chemical structures in mixtures by utilizing chromatographic and spectroscopic methods. However, current CASE tools still cannot automatically solve structures for experienced natural product chemists...

Autologous, patient-specific chimeric antigen receptor T-cell (CART) therapy has emerged as a powerful and potentially curative therapy for cancer, especially for CD19-positive hematological malignancies. Indeed, on August 30, 2017, the University of Pennsylvania-designed CD19-directed CART (CART-19) cell therapy (CTL019, tisagenlecleucel-t, Kymriah - Novartis) became the first CART therapy approved by the Food and Drug Administration (FDA) for acute lymphoblastic leukemia. However, the development of CART technology and its wider application is partly limited by the patient-specific nature of such a platform and by the time required for manufacturing...

Chemotherapy is limited by its poor selectivity towards cancer cells over normal cells. Herein, we designed half-sandwich ruthenium imino-pyridyl complexes [(η(6)-bz)Ru(N^N)Cl]PF6 to achieve selective cytotoxicity to cancer cells. This kind of ruthenium complex has unique characteristics and is worthy of further exploration in the design of new anticancer drugs.

Introduction: Primary focal segmental glomerulosclerosis (FSGS) is a leading cause of nephrotic syndrome and end-stage renal disease. There are no US Food and Drug Administration-approved therapies for FSGS, and treatment often fails to reduce proteinuria. Endothelin is an important factor in the pathophysiology of podocyte disorders, including FSGS. Sparsentan is a first-in-class, orally active, dual-acting angiotensin receptor blocker (ARB) and highly selective endothelin Type A receptor antagonist...
