Immunotherapy based on checkpoint blockade has been regarded as one of the most promising approaches towards many types of cancers. However, low response rate hinders its application due to insufficient tumor immunogenicity and immunosuppressive tumor microenvironment. To achieve an overall enhanced therapeutic outcome, we developed a dual-functional immuno-stimulatory polymeric prodrug carrier modified with pendent indoximod, an indoleamine 2,3-dioxygenase (IDO) inhibitor that can be used to reverse immune suppression, for co-delivery of Doxorubicin (Dox), a hydrophobic anticancer agent that can promote immunogenic cell death (ICD) and elicit antitumor immunity. The resulted carrier denoted as POEG-b-PVBIND, consisting of poly (oligo (ethylene glycol) methacrylate) (POEG) hydrophilic blocks and indoximod conjugated hydrophobic blocks, is rationally designed to improve immunotherapy by synergistically modulating the tumor microenvironment (TME). Our data showed that Dox-triggered ICD promoted intra-tumoral infiltration of CD8+ T cells and IFN-γ-production by CD8+ T cells. Meanwhile, cleaved indoximod significantly increased CD8+ T cell infiltration while reducing the immunosuppressive T regulatory cells (Tregs). More importantly, Dox/POEG-b-PVBIND micelles led to significantly improved tumor regression in an orthotopic murine breast cancer model compared to both Dox-loaded POEG-b-PVB micelles (a control inert carrier) and POEG-b-PVBIND micelles alone, confirming combination effect of indoximod and Dox in improving the overall antitumor activity. Indoleamine 2,3-dioxygenase (IDO) is an enzyme that can induce immune suppressive microenvironment in tumors. As a well-studied IDO inhibitor, indoximod (IND) represents a promising agent for cancer immunotherapy and could be particularly useful in combination with other chemotherapeutic agents. However, three major problems hinder its application: (1) IND is barely soluble in water; (2) IND delivery efficiency is limited (3) simultaneous delivery of two agents into tumor site is still challenging. Currently, most reports largely focus on improving the pharmacokinetic profile of IND alone via different formulations such as IND prodrug and IND nanocrystal. However, there is limited information about IND based co-delivery systems, especially for delivering hydrophobic chemotherapeutic agents. Here, we developed a new dual-functional polymeric prodrug carrier modified with a number of pendent IND units (denoted as POEG-b-PVBIND). POEG-b-PVBIND shows immunostimulatory and antitumor activities by itself. More importantly, POEG-b-PVBIND polymer is able to self-assemble into nano-sized micelles that are highly effective in formulating and codelivering other hydrophobic agents including doxorubicin (Dox), sunitinib (Sun), and daunorubicin (Dau), which can elicit antitumor immunity via promoting immunogenic cell death (ICD). We have shown that our new combination therapy led to a significantly improved antitumor activity in an aggressive murine breast cancer model (4T1.2).

A simple anodization technique has been adopted for the synthesis of Au doped TiO2 nanotubes (Au/TiO2NTs) electrode. The physicochem. properties of Au/TiO2NTs electrodes have been studied using FE-SEM, Raman spectroscopy, FTIR, XRD, and UV-vis DRS anal. techniques and, compared with un-doped TiO2NTs electrodes. The optimization of process parameters has been carried out for the photoelectrocatalytic (PEC) degradation of 4-CG (4-Chloroguaiacol) under batch-mode experiments Au/TiO2 nanotube electrodes showed 84% degradation efficiency in 6 h under optimized conditions viz. 0.15 mM Au loading, 0.08 g L-1 electrolyte concentration, 0.03 A current and pH 3 under UV light irradiations. The degradation of 4-CG was validated with the quantification of generated ·OH and degradation intermediates/byproducts during the batch-mode PEC treatment. PEC degradation of 4-CG has also been assessed in recirculation mode to study the feasibility of synthesized Au/TiO2NTs electrodes to treat large volume of contaminant polluted wastewater. For the feasibility of industrial scale applications, pulp and paper mill effluent was subjected to the PEC degradation under recirculation mode using Au/TiO2NTs electrodes and significant reduction in COD and TOC values were observed Overall, the cost of elec. energy consumption was computed for all the batch and recirculation-mode PEC treatment of 4-CG as well as real pulp and paper mill effluent.

A rarely explored oxidative ring contraction of electron-rich 1,2-diazine was described. Upon treatment with an electrophilic chlorinating reagent (TCICA), 1,4-dimethoxyphthalazines undergo an N-chlorination-induced ring contraction that was accompanied by the loss of one nitrogen atom. The scope of this unusual reactivity was examined with a range of 1,4-dimethoxyphthalazine derivatives In addition, a mechanism proceeding via a bicyclic species was proposed on the basis of an isolated reaction intermediate and DFT calculations

Belen’kii, L. I.; Gromova, G. P.; Krayushkin, M. M. published the artcile< Protonation and electrophilic trichloromethylation of 2,5- and 2,4-dichlorothiophenes>, Application In Synthesis of 31166-29-7, the main research area is electrophilic trichloromethylation chlorothiophene; protonation chlorothiophene.

Trichloromethylation of 2,5-dichlorothiophene (I) and 2,4-dichlorothiophene (II) with CCl4 and AlCl3 has been studied. The reaction of I was directed to position 3 with formation of 2,5-dichloro-3-(trichloromethyl)thiophene, the process being complicated by the formation of the isomeric 3,5-dichloro-2-(trichloromethyl)thiophene (III), and 4,5-dichloro-2-(trichloromethyl)thiophene, as well as linked products, i.e. a mixture of bis(dichlorothienyl)dichloromethanes. Trichloromethylation of II smoothly leads to III, along with a small amount of bis(3,5-dichloro-2-thienyl)dichloromethane. It was also found that as a result of protonation under the effect of HCland AlCl3, I was converted into II, which, under the reaction conditions exists in the form of σ-complex, i.e. the 2H-3,5-dichlorothiophenium ion, stable at room temperature The mechanism of trichloromethylation of I, including the ipso-attack by the CCl3+ cation and isomerization during protonation, is discussed.

The bradykinin 1 (B1) receptor is upregulated during times of inflammation and is important for maintaining inflamed and chronic pain states. Blocking this receptor has been shown to reverse and/or ameliorate pain and inflammation in animal models. In this report, we describe a new class of B1 receptor antagonists that contain the piperidine acetic acid tetralin core. A structure-activity relationship for these analogs is described in this paper. The most potent compounds from this class have IC50s < 20 nM in a B1 receptor functional assay. One of these compounds, I, shows modest oral bioavailability in rats.

Wang, Wen-Li; Jin, Ren-Hua published the artcile< A unique polymersome covered by loop-cluster polyamine corona>, Product Details of C9H9Cl, the main research area is methyloxazoline phenyloxazoline amphiphilic diblock RAFT polymerization self assembly.

In this work, we synthesized a new comb-like copolymer (c-iMP) possessing amphiphilic diblock side chains consisting of poly(methyloxazoline) (PMOZ) and poly(phenyloxazoline) (PPOZ) via reversible addition-fragmentation chain-transfer (RAFT) polymerization of p-choloromethylstyene (CMS) and cationic ring-opening polymerization (CROP) of 2-methyl-2-oxazoline (MOZ) and 2-phenyl-2-oxazoline (POZ). Then, by performing selective hydrolysis of the hydrophilic PMOZ block, the PMOZ block was transformed into PEI (polyethylenimine) from which comb-like copolymers (c-iEP) possessing two blocks of PEI (E) and PPOZ (P) were produced. The comb-copolymers c-iEP showed unique self-assembling behavior in water to give an unusual polymersome covered by a loop-cluster polyamine corona. The polymersome showed extreme toughness and stability without collapse and fusion even at dry conditions and could be transformed into capsules. This is the first example of polymersome without free-ends on the vesicle wall which could include Ag ions inside and could deposit silica around the wall to form hybrid hollow spheres.
