Development of Orally Bioavailable Amidobenzimidazole Analogues Targeting Stimulator of Interferon Gene (STING) Receptor.

Stimulator of interferon gene (STING) is a critical adaptor protein that has a pivotal role in triggering inherent immune responses to infection. STING-linked interferon production has been involved in anti-inflammation, anti-infection, and antitumor immunity. Herein, a series of amidobenzimidazole analogues as STING agonists were profiled for potency and drug-like properties.

[Effects of different proportions of red and blue light on the growth and photosynthesis of tomato seedlings].

In order to explore the mechanism of response of growth and development of tomato seedlings to the combination of red and blue light, the light-emitting-diodes (LEDs) as precision modulation light sources were used in this study with 7 treatments including red (R) light, blue (B) light and combination of R+B light (9R1B, 6R1B, 3R1B, 1R1B, 1R3B), white (W) light as control, and the effects of different proportions of R and B light on the growth, photosynthetic pigment content, photosynthetic characteristics, chlorophyll fluorescence and root activity of tomato seedlings with variety of 'SV0313TG' as experiment material were studied. The results showed that there were significant differences in growth of tomato seedlings under treatments of different proportions of R and B light. The plant height, specific leaf area and intercellular CO concentration of tomato seedlings were significantly promoted by R light, while F/F and χ were decreased, the root growth was inhibited as the root activity declined, so that the seedling index was reduced.
