Cholesteryl p-[3-(2-chloroethyl_-3-nitrosoureido] phenylthioaccetate (2) was synthesized : an intermediate, p-[3(2-chloroethyl_-3-nitrosoureido] phenylthioacetic acid (1) is a congener of an antitumor chlorambucil which both the -CH$_{2}$CH$_{2}$-linkage and -N(CH$_{2}$CH$_{2}$Cl)$_{2}$ group of chlorambucil molecule is doubly modified into the respective -S-linkage and -NH-CO-NNO-CH$_{2}$CH$_{2}$CL group. The attackment of cholesterol moiety as a carrier group to p-[3-(2-chloroethyl-3nitrosoureido] phenylthioacetic acid was accomplished through the esterification of cholesterol with p-[3-(2-chloroethyl-3-nitrosoureido] phenylthioacetyl chloride which was obtained from the treatment of p-[3-(2-chloroethyl)-3-nitrosourei-do] phenylthioaceticacid with SOCL$_{2}$, p-[3-(2-chloroethyl)ureido]]-phenythioacetic acid was nitrosated with NaNO$_{2}$ IN 98-100% HCOOH to give exclusively p-[3-(2-chloroethyl_-3-nitrosoureido] phenylthioacetic acid. Antitumor evaluation of compounds, 1 and 2 on L 1210 leukemia did show significant activity (ED$_{40}$ : 1.14.mu./ml and 8.4.mu.g/ml, repectively). Further studies were subjected..

Transcription factors (TF) can bind tightly to specific DNA lesions formed by some anticancer agents. The formation these TF:(drug-modified DNA) complex may disrupt expression of genes critical for cell survival, and it was proved to be one of biochemical mechanisms of anticancer activity. Based on this model, we have designed programmable DNA Alkylating agents that can also attract TF, especially nuclear receptors. As a model compound, we designed drug molecules, RA-mustard and Am580-mustard, that enable to bind both retinoic acid receptor (RAR) and DNA by using molecular modeling techniques, and synthesized them by connecting chlorambucil and ligand for RAR with a linker unit.

Background: Chronic lymphocytic leukemia (CLL) is the most frequent form of leukemia in Europe and North America, and it mainly affects older individuals. Many approaches are implemented in the management of CLL from a watch and wait (W&W) strategy to chemotherapeutic regimens. We here reviewed our clinical practice for the relevance of the W&W strategy in Lebanese CLL patients. Materials and Methods: A total of 95 patients with CLL diagnosed in four institutions in Lebanon, between 1992 and 2013, were selected and their files were reviewed. Characteristics of these patients were noted including age, sex, RAI and Binet scores, CBC values, presence of hepatomegaly or splenomegaly, performance of bone marrow biopsy or peripheral blood flux cytometry for diagnosis, adoption of W&W strategy, different chemotherapeutic regimens and the indications for treatment. Results: Some 38 patients (40%) diagnosed with CLL were women and 57 (60%) were men with a mean age of 65.1 years [36-89]. Of the total, 50.5%, 17.2%, 14%, 7.5% and 10.8% had an RAI score at diagnosis of 0, 1, 2, 3 and 4, respectively, while 65.6%, 17.2% and 17.2% had Binet scores of I, II and III. The mean lymphocyte count at diagnosis was $39885/mm^3$ [1596-290000], the mean hemoglobin level was 12.7 g/dl [6.2-17] and the mean platelet count was $191255/mm^3$ [14000-458000]. While 26.3% of patients with CLL had splenomegaly, only 7.4% had hepatomegaly. Some 33.7% had undergone a bone marrow biopsy, 66.3% flow cytometry of circulating blood and 5.3% a lymph node biopsy. Overall, the W&W was adopted in 62.4% (58) of patients with a mean duration of 37.7 months [3-216]. The W&W was used in 82.6%, 73.3%, 46.2%, 14.3% and 0% of patients having RAI scores of 0, 1, 2, 3 and 4, respectively, and, it was used in 80%, 46.7% and 6.25% with Binet scores of I, II and III. The most frequent indication for treatment was anemia and thrombocytopenia, accounting for 32.7% of cases. The most frequently used chemotherapeutical regimens were chlorambucil until the end of the last century and flufarabine-cyclophosphamide-rituximab during the last decade. Conclusions: This retrospective review of CLL clinical practice showed an important implementation of the W&W strategy with a long duration, especially in early stage cases with low RAI or Binet scores.

Objective : Membranous nephropathy (MN) is one of the most commonest forms of glomerular disease in man and the most frequent cause of the adult idiopathic nephrotic syndrome. Some investigators recommend no treatment, while others propose aggressive therapy, including prednisolone plus an immunosupressant such as chlorambucil or cyclophosphamide. But a more effective way to treat MN is not defined yet. This study was to evaluate the effects of Patriniae Radix extract (PRE) on the MN induced by cBSA in mice. Methods : Mice were divided into 4 groups. The first group (normal) was injected with saline. The second group (control) was treated with cBSA (10 mg/kg i.p) only. The third group, named PRE-2S0, was treated with cBSA (10 mg/kg i.p) and PRE (250 mg/kg, p.o). The fourth group, PRE-500, was treated with cBSA (10mg/kg i.p) and PRE (500mg/kg, p.o). After cBSA and PRE treatment for 4 weeks, we measured change of body weight, 24hrs proteinuria, serum albumin, total cholesterol, triglyceride, BUN, creatinine, IgG, IgA, IgM, $TNF-\alpha$, $IL-1\beta$, and $IFN-\gamma$ levels and the mRNA expression of $IFN-\gamma$, IL-6, and IL-10. The morphologic changes of renal glomeruli were also observed with a light microscope and an electron microscope. Results : The levels of 24 hrs proteinuria and serum triglyceride. BUN. IgG. $TNF-\alpha$, and $IL-1\beta$ significantly decreased in both PRE groups, while the level of serum albumin significantly increased in both PRE groups. The mRNA expression of IL-10 in splenocytes considerably increased in both PRE groups. The mRNA expression of $IFN-\gamma$ and IL-6 in splenocytes considerably increased in both PRE group. In histological findings of kidney tissue, thickening of GBM decreased in both PRE groups. Conclusions : The present study suggests that PRE is effective when treating mice with MN induced by cBSA. More clinical data and studies are to be done for efficient application.
