Wang, Jin published the artcileFolic Acid-Conjugated Pyropheophorbide a as the Photosensitizer Tested for In Vivo Targeted Photodynamic Therapy, Recommanded Product: 2-Chlorotrityl chloride, the publication is Journal of Pharmaceutical Sciences (2017), 106(6), 1482-1489, database is CAplus and MEDLINE.

Photodynamic therapy (PDT) is a highly localized and minimally invasive cancer treatment modality with many important advantages, but the lack of ideal photosensitizers (PSs) greatly restricts its clin. utility. To develop new PSs with highly efficient singlet oxygen production and high tumor-localizing ability to reduce damage to healthy adjacent tissues, we conjugated folic acid (FA) with pyropheophorbide a (Pyro), a potent PS with a very high singlet oxygen quantum yield and a high extinction coefficient In the present work, we describe the synthesis and PDT evaluation of this FA-Pyro conjugate both in vitro and in vivo. This conjugation increased the accumulation of Pyro inside the tumors and improved the efficiency of PDT, resulting in eradication of s.c. xenograft KB (human mouth epidermal carcinoma) tumors after only 1 or 2 applications of external near IR light irradiation This outstanding PDT outcome in a tumor-bearing mouse model and the simple synthesis of the conjugate should have very good practical potential for clin. application.

Luo, Qianfu published the artcileSynthesis and characteristics of dithienylethenes with purine and pyrimidine substituents, Application of 5-Chloro-3-[2-(5-chloro-2-methylthien-3-yl)cyclopent-1-en-1-yl]-2-methylthiophene, the publication is Dyes and Pigments (2015), 602-608, database is CAplus.

Five new dithienylethenes decorated with purine and pyrimidine derivatives have been conveniently synthesized via a facile one-pot process. All new compounds were characterized by ¹H NMR, ¹³C NMR, UV-visible spectroscopy and high-resolution mass spectrometry. Their photophys. properties and photochromic behavior were investigated in detail. These compounds exhibit reversible photochromism with good photocyclization/photocycloreversion quantum yields and considerable molar extinction coefficients The result shows that the introduction of purine and pyrimidine derivatives into the dithienylethene unit has a remarkable effect on their performance, such as photoinduced fatigue resistance, photocyclization/photocycloreversion quantum yields and molar extinction coefficient

Jin, Piaopiao published the artcileBinding porphyrins gated dithienylethene bridge, Formula: C15H14Cl2S2, the publication is Dyes and Pigments (2016), 151-158, database is CAplus.

Porphyrins strapped with photochromic dithienylethene have been prepared for photochem. double-throw gated switch. The strapped porphyrins performed totally different but reversible binding capacity and fluorescence intensity when irradiated by different lights. The photochromism of the dithienylethene bridge was effectively gated by porphyrin ring through binding or unbinding Zn²⁺. The central Zn²⁺ in the porphyrin ring was employed as a lock, external H⁺ as a key, which can alternately turn on/off the photochromic switch of the dithienylethene bridge. The porphyrins’ gate for binding/unbinding Zn²⁺ was reversibly regulated by dithienylethene switch with different irradiation lights. These distinctive properties might be utilized to multi-controlled mol. switches or logic gates.

Wang, Yan-Xiang published the artcileSynthesis and identification of novel berberine derivatives as potent inhibitors against TNF-α-induced NF-κB activation, Name: ((1S,4R)-7,7-Dimethyl-2-oxobicyclo[2.2.1]heptan-1-yl)methanesulfonyl chloride, the publication is Molecules (2017), 22(8), 1257/1-1257/14, database is CAplus and MEDLINE.

Twenty-three new berberine (BBR) analogs containing substituents on ring D, I [R¹ = OMe, NH₂, cyclopropanecarbonyloxy, (4-nitrophenyl)sulfonyloxy, etc., R² = OMe, (adamantan-1-yl)acetoxy, (adamantane-10-carbonyloxy)], were synthesized and evaluated for their activity for suppression of tumor necrosis factor (TNF)-α-induced nuclear factor (NF)-κB activation. Structure-activity relationship (SAR) anal. indicated that suitable tertiary/quaternary carbon substitutions at the 9-position or a rigid fragment at position 10 might be beneficial for enhancing their anti-inflammatory potency. Among them, compounds I [R¹ = (1-methylcyclohexane-1-carbonyl)oxy, 2-(bicyclo[2.2.1]heptan-2-yl)acetoxy, (2′-propylpentanoyl)oxy, (p-tert-butylbenzoyl)oxy, R² = OMe] exhibited satisfactory inhibitory potency against NF-κB activation, with an inhibitory rate of around 90% (5 μM), much better than BBR. A preliminary mechanism study revealed that all of them could inhibit TNF-α-induced NF-κB activation via impairing IκB kinase (IKK) phosphorylation as well as cytokines interleukin (IL)-6 and IL-8 induced by TNF-α. Therefore, the results provided powerful information on further structural modifications and development of BBR derivatives into a new class of anti-inflammatory candidates for the treatment of inflammatory diseases.
