The link of hedgehog (Hh) signaling activation to human cancer and synthesis of a variety of Hh signaling inhibitors raise great expectation that inhibiting Hh signaling may be effective in human cancer treatment. Cyclopamine (Cyc), an alkaloid from the Veratrum plant, is a specific natural product
Targeted inhibition of hedgehog signaling by cyclopamine prodrugs for advanced prostate cancer.

A promising agent for use in prostate cancer therapy is the Hedgehog (Hh) signaling pathway inhibitor, cyclopamine. This compound, however, has the potential for causing serious side effects in non-tumor tissues. To minimize these bystander toxicities, we have designed and synthesized two novel
Combination therapy of paclitaxel and cyclopamine polymer-drug conjugates to treat advanced prostate cancer.

Repeated treatments with chemotherapeutic agent(s) fail due to cancer stem cells (CSCs) and chemoresistance regulated by microRNAs (miRNA) whose expression alters owing to dysfunctional signaling pathways including Hedgehog (Hh) signaling. We previously demonstrated the combination of Hh inhibitor
Combined targeting of epidermal growth factor receptor and hedgehog signaling by gefitinib and cyclopamine cooperatively improves the cytotoxic effects of docetaxel on metastatic prostate cancer cells.

The epidermal growth factor receptor (EGFR) and hedgehog cascades provide a critical role in prostate cancer progression and contribute to the resistance to clinical therapies and disease relapse. Therefore, we evaluated, for the first time, the antiproliferative and cytotoxic effects induced by a
Cyclopamine tartrate, an inhibitor of Hedgehog signaling, strongly interferes with mitochondrial function and suppresses aerobic respiration in lung cancer cells.

BACKGROUND
Aberrant Hedgehog (Hh) signaling is associated with the development of many cancers including prostate cancer, gastrointestinal cancer, lung cancer, pancreatic cancer, ovarian cancer, and basal cell carcinoma. The Hh signaling pathway has been one of the most intensely investigated
Cyclopamine increases the cytotoxic effects of paclitaxel and radiation but not cisplatin and gemcitabine in Hedgehog expressing pancreatic cancer cells.

BACKGROUND
The hedgehog signaling pathway (Hh) is frequently over expressed in pancreatic adenocarcinomas. We studied the potential cytotoxic interactions between cyclopamine, a Hh pathway inhibitor and paclitaxel, cisplatin, gemcitabine and ionizing radiation (IR).
METHODS
In vitro clonogenic
Co-delivery of Cyclopamine and Doxorubicin Mediated by Bovine Serum Albumin Nanoparticles Reverses Doxorubicin Resistance in Breast Cancer by Down-regulating P-glycoprotein Expression.

Combination chemotherapy is considered to be one of the most effective treatments for breast cancer by reducing the emergence of drug resistance. In this study, a novel drug delivery system based on bovine serum albumin nanoparticles (BSA NPs) was successfully developed. Doxorubicin (DOX) and
Gli3 silencing enhances cyclopamine suppressive effects on ovarian cancer.

Ovarian cancer is a leading gynecological malignancy associated with high mortality. Hedgehog signaling has been found to be important for cell proliferation and tumor growth for multiple cancers, including ovarian cancer. The present study showed that the drug cyclopamine, which blocks the hedgehog

Elevated expression of the efflux transporter, ATP-binding cassette subfamily G isoform 2 (ABCG2) on the plasma membrane of cancer cells contributes to the development of drug resistance and is a key characteristic of cancer stem cells. In this study, gene expression analysis identified that

The Hedgehog signalling pathway plays a critical role in controlling growth, especially during development, but is often over-activated in tumourigenesis. It has recently emerged as an important target for anticancer drugs, with several compounds in clinical trials. This review initially describes
Isocyclopamine, a novel synthetic derivative of cyclopamine, reverts doxorubicin resistance in MCF-7/ADR cells by increasing intracellular doxorubicin accumulation and downregulating breast cancer stem-like cells.

Cyclopamine (CPM) showed promise as a human cancer chemotherapy agent. However, limitations such as stomach acid instability and low solubility impair its clinical application. In this study, we synthesized a novel CPM analogue, isocyclopamine (ICPM), which had comparative bioactivity with CPM and
The Hedgehog inhibitor cyclopamine impairs the benefits of immunotherapy with activated T and NK lymphocytes derived from patients with advanced cancer.

Hedgehog (Hh) signaling is activated in various types of cancer and contributes to the progression, proliferation, and invasiveness of cancer cells. Many Hh inhibitors are undergoing clinical trial and show promise as anticancer drugs. Hh signaling is also induced in the activated T and NK (TNK)

Although the blockade of the hedgehog cascade by using cyclopamine has been reported to inhibit the growth of some cancer cell types, few studies on the mechanism by which this drug alone or in combination with other cytotoxic agents induces its cytotoxic effect have been reported. In our study, we

Lung cancer remains the leading cause of cancer-related death, despite the advent of targeted therapies and immunotherapies. Therefore, it is crucial to identify novel molecular features unique to lung tumors. Here, we show that cyclopamine tartrate (CycT) strongly suppresses the growth of
