Breast cancer is the most common cancer in women worldwide. Estrogen signaling pathways have been identified as efficient targets of breast cancer therapy, given their key role in promoting breast tumor growth. Agents blocking estrogen-mediated pathways are routinely used in clinical applications in patients displaying estrogen-sensitive breast cancer subtypes;however intrinsic or acquired resistance to treatment often occurs or develops, thus limiting their efficacy. This limitation has highlighted an imperative need to identify new predictive biomarkers. Recent findings have highlighted a role for the Liver Kinase B1 (LKB1) in breast cancer tumorigenesis. LKB1 is a serine/threonine kinase mutated in Peutz-Jeghers syndrome (PJS), implicated in many cellular processes including energy metabolism, cell polarization and cell cycle arrest and has also been shown to play an essential role as a tumor suppressor gene by negatively regulating the mTOR pathway. This review provides an overview of previous findings and ongoing research on LKB1, and substantiates the use of this kinase as a potential prognostic and predictive biomarker of breast cancer.

Synthesis and Structure-Activity Relationships of Novel Neocryptolepine Derivatives

Herein we reported the synthesis of a novel series of neocryptolepine（5-methyl-5H-indolo[2,3-b]quinoline） derivatives containing different substituents at Cll using methyl 1H-indole-3-carboxylate and N-methylaniline as starting material. The target 21 compounds were evaluated for their axltibacterial activity in vitro against gram-positive bacteria（B, subtilis and S. aureus） and gram-negative bacteria（E, coli and ***）. Almost all the tested compounds showed moderate to high activities against the four bacterial strains at the minimum inhibitory concentrations（MICs） of 1-10μg/mL. The obtained results suggest that part of the novel synthetic neocryptolepine derivatives exhibit significant antibacterial effect against all the tested organisms.
