Reassignment of Improbable Natural Products Identified through Chemical Principle Screening

Selective chemical probe inhibitor of Stat3, identified through structure-based virtual screening, induces antitumor activity.

S3I-201 (NSC 74859) is a chemical probe inhibitor of Stat3 activity, which was identified from the National Cancer Institute chemical libraries by using structure-based virtual screening with a computer model of the Stat3 SH2 domain bound to its Stat3 phosphotyrosine peptide derived from the x-ray crystal structure of the Stat3beta homodimer. S3I-201 inhibits Stat3.Stat3 complex formation and S...

Exposing the Molecular Screening Method of Indonesian Natural Products Derivate as Drug Candidates for Cervical Cancer

The menace of cervical cancer has reached an alarming rate. There are more than 450.000cases of cervical cancer yearly, with mortality rate of about 50%. This deadly cancer is causedby human papillomavirus (HPV), mainly subtypes 16 and 18. The pharmaceutical industryhas produced drug for combating the virus, known as SAHA (suberoylanilide hydroxamicacid). It inhibits class II HDAC Homo sapiens ...

Novel Abscisic Acid Antagonists Identified with Chemical Array Screening.

Abscisic acid (ABA) signaling is involved in multiple processes in plants, such as water stress control and seed dormancy. Major regulators of ABA signaling are the PYR/PYL/RCAR family receptor proteins, group A protein phosphatases 2C (PP2Cs), and subclass III of SNF1-related protein kinase 2 (SnRK2). Novel ABA agonists and antagonists to modulate the functions of these proteins would not only...
