We present a system that produces sentential descriptions of video: who did what to whom, and where and how they did it. Action class is rendered as a verb, participant objects as noun phrases, properties of those objects as adjectival modifiers in those noun phrases, spatial relations between those participants as prepositional phrases, and characteristics(More)
Heat shock protein 90 (Hsp90), whose inhibitors have shown promising activity in clinical trials, is an attractive anticancer target. In this work, we first explored the significant pharmacophore features needed for Hsp90 inhibitors by generating a 3D-QSAR pharmacophore model. It was then used to virtually screen the SPECS databases, identifying 17 hits.(More)
Kv1.5 potassium channel is an efficacious and safe therapeutic target for the treatment of atrial fibrillation (AF), the most common arrhythmia that threatens human. Herein, by modifying the hit compound 7k from an in-house database, 48 derivatives were synthesized for the assay of their Kv1.5 inhibitory effects by whole cell patch clamp technique. Six(More)
We present an approach to labeling short video clips with English verbs as event descriptions. A key distinguishing aspect of this work is that it labels videos with verbs that describe the spatiotemporal interaction between event participants, humans and objects interacting with each other, abstracting away all object-class information and fine-grained(More)
p53 protein is a prominent tumor suppressor to induce cell cycle arrest, apoptosis and senescence, which attracts significant interest to cancer treatment. Therefore, it would be particularly important to restore the wild-type p53 that retains latent functions in the approximately 50% of tumors. MDM2 (murine double minute 2), the principal cellular(More)
Hypoxia-inducible factor-1 (HIF-1) as a key mediator in tumor metastasis, angiogenesis, and poor patient prognosis has been recognized as an important cancer drug target. A novel series of N-(benzofuran-5-yl)aromaticsulfonamide derivatives were synthesized and evaluated as HIF-1 inhibitor. Among these compounds, 7q exhibited specific inhibitory effects on(More)
