OBJECTIVE: Tumor necrosis factor (TNF) related apoptosis inducing ligand (TRAIL) can induce the apoptosis of tumor cells, but leaving its effect on malignant lymphoma largely insignificant, as these tumors may develop drug resistance. Chlorambucil (CLB) had definitive treatment efficacy on low-malignant non-Hodgkin lymphoma (NHL), but with unclear efficacy on highly malignant Burkitt lymphoma. A study has been shown that CLB could enhance the sensitivity of chronic lymphatic leukemia cells against TRAIL...

Systemic administration of corticosteroid (CS) remains the standard gold treatment for pemphigus. However, because of several long-term adverse effects, steroid-sparing agents are usually prescribed in combination with CSs. Despite the high number of available studies, the choice of best drugs to treat pemphigus remains controversial. Therapeutic approaches for pemphigus can be divided into traditional treatment and emerging ones. Personalized medicine, which aims to increase the efficacy as well as reduce adverse effects of treatments, could be considered as the future option...

Elderly patients with chronic lymphocytic leukemia (CLL) or patients with comorbidities are often treated with chlorambucil (Chl) as front-line therapy despite relatively low response rates. The addition of a monoclonal anti-CD20 antibody to Chl substantially increases response rates and prolongs progression-free survival (PFS) in these patients, without increasing toxicity. As a result, the ESMO guidelines recommend that previously untreated CLL patients with relevant co-morbidity, but without TP53 deletion/mutation, should be treated with the combination of Chl plus an anti-CD20 antibody (rituximab, ofatumumab or obinutuzumab)...

Background: Advanced-stage mycosis fungoides (MF)/Sézary syndrome (SS) patients are weighted by an unfavorable prognosis and share an unmet clinical need of effective treatments. International guidelines are available detailing treatment options for the different stages but without recommending treatments in any particular order due to lack of comparative trials. The aims of this second CLIC study were to retrospectively analyze the pattern of care worldwide for advanced-stage MF/SS patients, the distribution of treatments according to geographical areas (USA versus non-USA), and whether the heterogeneity of approaches has potential impact on survival...

Nitrogen mustards, such as chlorambucil (CLB), can cause adverse side-effects due to ubiquitous distribution in non-target organs. To minimize this toxicity, strategies of tumor-targeting drug delivery have been developed, where a cytotoxic warhead is linked to a tumor-cell-specific small ligand. Malignant cells exhibit marked glucose avidity and an accelerated metabolism by aerobic glycolysis, known as the Warburg effect, and recognized as a hallmark of cancer. A targeting approach exploiting the Warburg effect by conjugation of CLB to 2-fluoro-2-deoxyglucose (FDG) was previously reported and identified two peracetylated glucoconjugates 2 and 3 with promising antitumor activities in vivo...

Two hybrids of Pt(IV) species were designed and prepared by addition of a chlorambucil unit to the axial positions of the Pt(IV) complexes derived from DN603 and DN604. In vitro studies of two hybrids against two pairs of cisplatin sensitive and resistant cancer cell lines indicated that compound 5 had superior antitumor activity to cisplatin and chlorambucil via suppressing DNA damage repair to reverse drug resistance. Mechanistic investigation suggested that the potent antitumor activity of compound 5 arose from its major suppression of CK2-mediated MRE11-RAD50-NBS1(MRN) complex promotion of DNA double-strand break (DSB) repair...

Exposure to Agent Orange (AO) has been associated with the development of chronic lymphocytic leukemia (CLL). We performed a retrospective study of 2052 Vietnam veterans identified in the National VA Tumor Registry to assess the impact of AO exposure on CLL prognosis, treatment and survival. Prognostic factors did not differ based on exposure. Veterans exposed to AO were diagnosed younger (63.2 vs. 70.5 years, p < .0001) and had longer overall survival (median not reached vs. 91 months, p < .001)...

BACKGROUND: Immunosuppressive agents in general are shown to prevent renal progression and all-cause mortality in idiopathic membranous nephropathy (IMN) patients with nephrotic syndrome. However, the efficacy and safety of different immunosuppressive treatments have not been systematic assessed and compared. A network meta-analysis was performed to compare different immunosuppressive treatment in IMN. METHODS: Cochrane library, MEDLINE, EMBASE and trial register system were searched for randomized controlled trials reporting the treatments for IMN to May 3, 2016...

Metastatic castration-resistant prostate cancer (mCRPC) remains essentially incurable. Targeted Drug Delivery (TDD) systems may overcome the limitations of current mCRPC therapies. We describe the use of strict criteria to isolate novel prostate cancer cell targeting peptides that specifically deliver drugs into target cells. Phage from a libraries displaying 7mer peptides were exposed to PC-3 cells and only internalized phage were recovered. The ability of these phage to internalize into other prostate cancer cells (LNCaP, DU-145) was validated...

Here we report the first of the phenosafranin-chlorambucil conjugate as a new type of a chemotherapeutic agent suitable for dual detection methods (spectrophotometric and fluorescence) in imaging systems and cancer treatment. The synthetic cationic dye (3,7-diamino-5-phenylphenazinium chloride) is used as a fluorescent light-triggered scaffold that acts as a carrier for an anti-cancer drug. The chlorambucil was attached covalently via amide bonds to the bifunctional fluorophore, which facilitates tracking with visible light...

Dear Editor, An 83-year-old woman developed yellow-brownish infiltrates, nodules, and tumors mimicking xanthomas, mostly involving the periorbital and chest area within three months (Figure 1). She had no abnormalities in serum cholesterol or triglycerides levels. A detailed laboratory analysis revealed the presence of mild monoclonal gammopathy with a presence of immunoglobulin G (IgG) kappa light chains; however, according to hematologist consultation, it did not require medical intervention. Imaging assessment and ultrasound examination did not show any specific involvement of internal organs...

Myasthenia gravis (MG) is an autoimmune disease of the neuromuscular junction, characterized by fatigable weakness of the extraocular, bulbar, and limb musculature; prevalence is estimated at 14 to 32 per 100,000 in North America. Chronic lymphocytic leukemia (CLL) is the most common type of leukemia in adults, resulting from clonal expansion of B-cells in blood, marrow, and secondary lymphoid tissues. The simultaneous presentation of MG and CLL is exceedingly rare. This article presents the case of 71-year-old man diagnosed simultaneously with MG and CLL...

For synergistic cancer therapy, it is highly desirable to devise a single multifunctional agent to combine photodynamic therapy (PDT), photothermal therapy (PTT), and chemotherapy, which is soluble and excitable at low irradiation, as well as able to selectively target tumors and achieve high efficacy. Toward this ambition, here the chemotherapy drugs chlorambucil (Cb), and all trans retinoic acid (ATRA) are covalently conjugated onto a small dye molecule diketopyrrolopyrrole (DPP-Cb and DPP-ATRA). The soluble nanoparticles (NPs) of DPP-Cb and DPP-ATRA formed by reprecipitation can selectively accumulate in tumors, release chemotherapy drugs under acidic conditions, and exhibit efficient reactive oxygen species (ROS) generation and photothermal conversion under the irradiation of a low power xenon lamp (40 mW/cm(2))...

Multidrug resistance (MDR) limits the application of a large number of cancer-fighting agents in clinical therapy. One reason is that P-glycoprotein (Pgp) efflux pumps are usually overexpressed and lead to drug efflux in the cancer cells, which limits the viability of many chemotherapeutics. Current available inhibitors which block the Pgp pump efflux are usually not widely used in clinical practice, because they change other drug pharmacokinetic profiles or increase side effects. Here, through covalent linkage of cancer-targeting delocalized lipophilic cation FF and DNA-damaging drug nitrogen mustard chlorambucil (CLB), we rationally designed and synthesized a tumor-targeting anticancer agent FFCLB...

Histone deacetylases (HDACs) play a pivotal role not only in gene expression but also in DNA repair. Herein, we report the successful design, synthesis and evaluation of a chlorambucil derivative named vorambucil with a hydroxamic acid tail as a DNA/HDAC dual-targeting inhibitor. Vorambucil obtained both potent DNA and HDACs inhibitory activities. Molecular docking results supported the initial pharmacophoric hypothesis and rationalized the potent inhibitory activity of vorambucil against HDAC1, HDAC2 and HDAC6...
