Abstract
Glucose-responsive system is one of important options for self-regulated insulin delivery to treat diabetes, which has become an issue of great public health concern in the world. In this study, we developed a novel and biocompatible glucose-responsive insulin delivery system using a pH-sensitive peptide hydrogel as a carrier loaded with glucose oxidase, catalase and insulin. The peptide could self-assemble into hydrogel under physiological conditions. When hypoglycemia is encountered, neighboring alkaline amino acid side chains are significantly repulsed due to reduced local pH by the enzymatic conversion of glucose into gluconic acid. This is followed by unfolding of individual hairpins, disassembly and release of insulin. The glucose-responsive hydrogel system was characterized on the basis of structure, conformation, rheology, morphology, acid-sensitivity and the amount of consistent release of insulin in vitro and vivo. The results illustrated that our system can not only regulate the blood glucose levels in vitro but also in mice models having STZ-induced diabetes. STATEMENT OF SIGNIFICANCE In this report, we have shown the following significance supported by the experimental results. 1. We successfully developed, characterized and screened a novel pH-responsive peptide. 2. We successfully developed a novel and biocompatible pH-sensitive peptide hydrogel as glucose-responsive insulin delivery system loaded with glucose oxidase, catalase and insulin. 3. We successfully confirmed that the hydrogel platform could regulate the blood glucose level in vitro and in vivo. Overall, we have shown enough significance and novelty with this smart hydrogel platform in terms of biomaterials, peptide chemistry, self-assembly, hydrogel and drug delivery. So we believe this manuscript is suitable for Acta Biomaterialia.

Site-specific fatty chain-modified exenatide analogs with balanced glucoregulatory activity and prolonged in vivo activity. Biochem Pharmacol 2016; 110-111:80-91.

Abstract
The therapeutic utility of exenatide (Ex-4) is limited due to short plasma half-life of 2.4h and thus numerous approaches have been used to obtain a longer action time. However, such strategies often attend to one thing and lose another. The study aimed to identify a candidate with balanced glucoregulatory activity and prolonged in vivo activity. A series of fatty chain conjugates of Ex-4 were designed and synthesized. First, thirteen cysteine modified peptides (1-13) were prepared. Peptides 1, 10, and 13 showed improved glucagon-like peptide-1 (GLP-1) receptor activate potency and were thus selected for second step modifications to yield conjugates I-1-I-9. All conjugates retained significant GLP-1 receptor activate potency and more importantly exerted enhanced albumin-binding properties and in vitro plasma stability. The protracted antidiabetic effects of the most stable I-3 were further confirmed by both multiple intraperitoneal glucose tolerance test and hypoglycemic efficacies test in vivo. Furthermore, once daily injection of I-3 to streptozotocin (STZ) induced diabetic mice achieved long-term beneficial effects on hemoglobin A1C (HbA1C) lowering and glucose tolerance. Once daily injection of I-3 to diet induced obesity (DIO) mice also achieved favorable effects on food intake, body weight, and blood chemistry. Our results suggested that I-3 was a promising agent deserving further investigation to treat obesity patients with diabetes.

Abstract
Three series of Momordica charantia (MC)2 analogues were designed, synthesized and evaluated for their anti-hyperglycaemic effects. Alanine scanning focusing on the peptide MC2 indicated the importance of the residues proline (Pro)(3), serine (Ser)(6), isoleucine (Ile)(7) and Ser(10) for anti-hyperglycaemic effects. Among the first series of MC2 analogues, peptide I-4 exhibited a better anti-hyperglycaemic effect and was chosen for further modification. A further two series of conformationally constrained analogues were designed by scanning the residues Pro(3), Ser(6), Ile(7), and Ser(10) with an i - (i + 2) lactam bridge consisting of a glutamic acid-Xaa-lysine (Glu-Xaa-Lys) scaffold and a diproline fragment. By screening in normal mice and mice with diabetes mellitus, peptides II-1, II-2 and III-3 showed a significant improvement in anti-hyperglycaemic and anti-oxidative activities compared with I-4. These data suggest that II-1, II-2 and III-3 could be candidates for future treatment of diabetes mellitus.
