Breast carcinoma is the most common female cancer with considerable metastatic potential. Discovery of new therapeutic approaches for treatment of metastatic breast cancer is still needed. Here, we reported our finding with niclosamide, an FDA approved anthelmintic drug. The potency of niclosamide on breast cancer was assessed in vitro and in vivo. In this(More)
Melanoma is a highly malignant neoplasm of melanocytes with considerable metastatic potential and drug resistance, explaining the need for new candidates that inhibit tumor growth and metastasis. The signal transducer and activator of the transcription 3 (Stat3) signaling pathway plays an important role in melanoma and has been validated as promising(More)
Enhancer of zeste homolog 2 (EZH2) is a candidate oncogenic driver due to its prevalent overexpression and aberrant repression of tumor suppressor genes in diverse cancers. Therefore, blocking EZH2 enzyme activity may present a valid therapeutic strategy for the treatment of cancers with EZH2 overexpression including breast cancers. Here, we described(More)
BACKGROUND Cancer is still a major public health issue worldwide, and new therapeutics with anti-tumor activity are still urgently needed. METHODS The anti-tumor activity of TH-39, which shows potent anti-proliferative activity against K562 cells with an IC50 of 0.78 µM, was investigated using immunoblot, co-immunoprecipitation, the MTT assay, and flow(More)
CONTEXT Periplaneta americana L. (Dictyoptera; Blattaria) has been traditional used to treat ulcers, burns and heart disease in southwestern China. Recent reports indicate that P. americana can be used as an alternative medicine in therapy of ulcerative colitis, but the mechanism involved remains obscure. OBJECTIVE This study investigated the therapeutic(More)
New chemotherapeutic compounds are needed to combat multidrug-resistant Mycobacterium tuberculosis (Mtb), which remains a serious public-health challenge. Decaprenylphosphoryl-β-D-ribose 2'-epimerase (DprE1 enzyme) has been characterized as an attractive therapeutic target to address this urgent demand. Herein, we have identified a new class of DprE1(More)
EZH2 (Enhancer of zeste homolog 2) is the catalytic subunit of the polycomb repressive complex 2 (PRC2), which is involved in repressing gene expression by methylating lysine 27 of histone H3 (H3K27) and regulates cell proliferation. EZH2 overexpression is implicated in tumorigenesis and has been a candidate oncogene in several tumor types. Recently, point(More)
A series of novel polycyclic spiro-fused carbocyclicoxindoles were synthesized and investigated for their in vitro antiproliferative activities against nine human cancer cell lines. Five compounds (10i, 10l, 10n, 10p, and 10r) demonstrated anticancer activities against A2780s cells with IC50 values of less than 30 μM. In particular, compound 10i showed(More)
Pancreatic carcinoma is a still unsolved health problem all over the world with poor prognosis and high mortality rate. YLT256, a novel synthesized chemical small inhibitor, displays potent antineoplastic activities via inducing apoptosis both in vitro and in vivo. In this study, we found that YLT256 showed growth inhibition against a broad spectrum of(More)
