Author is Caruso, Enrico; Malacarne, Miryam C.; Marras, Emanuela; Papa, Ester; Bertato, Linda; Banfi, Stefano; Gariboldi, Marzia B..

A new class of compounds based on the 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene core, known as BODIPYs, has attracted significant attention as photosensitizers suitable for application in photodynamic therapy (PDT), which is a minimally invasive procedure to treat cancer. In PDT the combination of a photosensitizer (PS), light and oxygen leads to a series of photochem. reactions generating reactive oxygen species (ROS) exerting cytotoxic action on tumor cells. Herein is presented the synthesis and the study of the in vitro photodynamic effects of two BODIPYs (I, n=4,8) which differ in the structure of the substituent placed on the meso (or 8) position of the dipyrrolylmethenic nucleus. The two compounds were tested on three human cancer cell lines of different origin and degree of malignancy. Our results indicate that the BODIPYs are very effective in reducing the growth/viability of HCT116, SKOV3 and MCF7 cells when irradiated with a green LED source, whereas they are practically devoid of activity in the dark. Phototoxicity occurs mainly through apoptotic cell death, however necrotic cell death also seems to play a role. Furthermore, singlet oxygen generation and induction of the increase of reactive oxygen species also appear to be involved in the photodynamic effect of the BODIPYs. Finally, it is worth noting that the two BODIPYs are also able to exert anti-migratory activity.

Author is Chen, Xi; Liu, Yu-Cong; Cui, Jing-Jing; Wu, Fang-Ying; Xiao, Qiang.

Pathogenic E. coli infection is one of the most widespread foodborne diseases, so the development of sensitive, reliable and easy operating detection tests is a key issue for food safety. Identifying bacteria with a fluorescent medium is more sensitive and faster than using chromogenic media. This study designed and synthesized a β-galactosidase-activatable fluorescent probe BOD-Gal for the sensitive detection of E. coli. It employed a biocompatible and photostable 4,4-difluoro-3a,4a-diaza-s-indancene (BODIPY) as the fluorophore to form a β-O-glycosidic bond with galactose, allowing the BOD-Gal to show significant on-off fluorescent signals for in vitro and in vivo bacterial detection. This work shows the potential for the use of a BODIPY based enzyme substrate for pathogen detection.

Two novel, self-reporting distyryl BODIPY-based photodynamic therapy agents functionalized with singlet oxygen responsive imidazole and tertiary amine moieties are developed. Heavy atom-free photosensitizers are demonstrated to have efficient photodynamic action in MCF7 cells. The fluorescence intensity of the photosensitizers is shown to be reduced as a result of 1O2 generation without any significant change in photodynamic activity.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 625-82-1, is researched, Molecular C6H9N, about Syntheses, kinetics and thermodynamics of BODIPY-based fluorescent probes with different kinds of hydrophilic groups for the detection of biothiols, the main research direction is BODIPY fluorescence probe biothiol.Formula: C6H9N.

A series of BODIPY-based fluorescent probes incorporating different kinds of hydrophilic groups were synthesized for the detection of biothiols (GSH as a representative target), namely BDP (control), BDP-OH (acidic), BDP-OEG (neutral and hydrophilic) and BDP-QA (cationic). The incorporation of nitroolefin unit (-CH=CH-NO2) to the BODIPY core enabled the OFF-ON fluorescent probes. The results indicated that the absorption and fluorescence emission spectra of the probes were essentially not affected by the hydrophilic groups attached on the para position of the meso Ph group. The reaction rate constants were affected by the hydrophilicity of probes. It was highly worth noting that the cationic BDP-QA had the fastest response toward biothiols owing to the best water solubility and the possible formation of ion pairs with thiolate (R-S-). Thermodn. illustrated that the reactions of probes with GSH all had neg. enthalpy changes and neg. entropy changes. Moreover, BDP-QA had the highest affinity toward GSH (K = 2.54 x 104 M-1) and the smallest LOD value (182 nΜ), which benefited from its best water solubility This work has primarily elucidated the effects of hydrophilic groups from the kinetic and thermodn. perspectives. It will promote better design of fluorescent probes with fast response and high affinity.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 2,4-Dimethyl-1H-pyrrole( cas:625-82-1 ) is researched.Computed Properties of C6H9N.Yan, Ziling; Wang, Mengya; Shi, Mengke; He, Yang; Zhang, Yi; Qiu, Shihong; Yang, Hong; Chen, Huabing; He, Hui; Guo, Zhengqing published the article 《Amphiphilic BODIPY dye aggregates in polymeric micelles for wavelength-dependent photo-induced cancer therapy》 about this compound( cas:625-82-1 ) in Journal of Materials Chemistry B: Materials for Biology and Medicine. Keywords: BODIPY dye micelle cancer phototherapy. Let’s learn more about this compound (cas:625-82-1).

Near-IR (NIR) light-responsive nanoparticles of organic small-mol. dyes hold great promise as phototherapeutic dyes (PDs) for clin. translation due to their intrinsic merits, including well-defined structure, high purity, and good reproducibility. However, they have been explored with limited success in the development of photostable NIR PDs with extraordinary photoconversion for highly effective phototherapy. Herein, we have described amphiphilic BODIPY dye aggregates within the polymeric micelles (Micelles) as potent bifunctional PDs for dually cooperative phototherapy under NIR irradiation Micelles possessed an intensive NIR absorption, high photostability, and favorable non-radiative transition, thereby exhibiting both remarkable singlet oxygen generation and photothermal effect under NIR light irradiation Besides, Micelles had preferable cellular uptake, effective cytoplasmic drug translocation as well as enhanced tumor accumulation. Owing to the combined virtues, Micelles showed clin. potential as bifunctional PDs for photo-induced cancer therapy. This work thus provides a facile strategy to exploit advanced PDs for practical phototherapeutic applications.

Quality Control of 2,4-Dimethyl-1H-pyrrole. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 2,4-Dimethyl-1H-pyrrole, is researched, Molecular C6H9N, CAS is 625-82-1, about A highly-efficient type I photosensitizer with robust vascular-disruption activity for hypoxic-and-metastatic tumor specific photodynamic therapy. Author is Chen, Dapeng; Yu, Qing; Huang, Xuan; Dai, Hanming; Luo, Tao; Shao, Jinjun; Chen, Peng; Chen, Jie; Huang, Wei; Dong, Xiaochen.

Hypoxia severely impedes photodynamic therapy (PDT) efficiency. Worse still, considerable tumor metastasis will occur after PDT. Herein, an organic superoxide radical (O2·-) nano-photogenerator as a highly efficient type I photosensitizer with robust vascular-disrupting efficiency to combat these thorny issues is designed. Boron difluoride dipyrromethene (BODIPY)-vadimezan conjugate (BDPVDA) is synthesized and enwrapped in electron-rich polymer-brushes methoxy-poly(ethylene glycol)-b-poly(2-(diisopropylamino) Et methacrylate) (mPEG- PPDA) to afford nanosized hydrophilic type I photosensitizer (PBV NPs). Owing to outstanding core-shell intermol. electron transfer between BDPVDA and mPEG-PPDA, remarkable O2·- can be produced by PBV NPs under near-IR irradiation even in severe hypoxic environment (2% O2), thus to accomplish effective hypoxic-tumor elimination. Simultaneously, the efficient ester-bond hydrolysis of BDPVDA in the acidic tumor microenvironment allows vadimezan release from PBV NPs to disrupt vasculature, facilitating the shut-down of metastatic pathways. As a result, PBV NPs will not only be powerful in resolving the paradox between traditional type II PDT and hypoxia, but also successfully prevent tumor metastasis after type I PDT treatment (no secondary-tumors found in 70 days and 100% survival rate), enabling enhancement of existing hypoxic-and-metastatic tumor treatment.
