DASATINIB- A DRUG OF CHOICE

7170 | Jun 04 2012

INTRODUCTION Diverse types of cellular systems are there in human bodies that differ structurally and functionally from one another. Each cellular system is controlled by a variety of controllers called cell cycle regulatory proteins. Defective controllers may lead to abnormal cellular systems and the condition known as cancer may develop. Cancer may be of different types depending upon the defect in the cell cycle regulatory proteins. Cancer may also vary on the basis of stage of the defective condition. Many therapies have been devised in order to treat cancerous cells. Further research is also being done for developing better, more specific and less toxic therapies and to cope with the development of resistance in the defective cells against existing therapies. Besides resistance, metastasis is also another issue to be resolved in case of cancerous cells. Imatinib has been used against leukemia for several years but due to high levels of toxicity scientists discovered a new drug, called Dasatinib, for the same therapy. Dasatinib BMS-354825 is more efficient and less toxic as compared to Imatinib. The drug is being marketed by the name of Sprycel. As Dasatinib was discovered by Jagabandhu Das, it was named Dasatinib. Development of the drug was done by Squibb Company. [Read the Full Post]

ENZASTAURIN AGAINST MALIGNANCIES

4216 | Mar 20 2012

Introduction: The Protein Kinase C family A cytosolic protein kinase isolated in the late 1970’s by the Nishizuka group of Kobe University, Japan has been found to be a key factor in the regulation of the cell cycle. Established as the protein kinase C family several isoforms have subsequently be isolated. These serine / threonine kinases are activated by the diacylglycerol (DAG) which is generated by the agonist induced hydrolysis of Trans-membrane G-protein kinases or tyrosine kinases. Activation of protein kinase C leads to a movement of the protein to the either the cytosolic skeleton or to the cellular membrane triggering a cascade of downstream signals which induce cell growth, differentiation or proliferation activities, this process appears to be mediated by the release of Ca2+. One of the key elements to be discovered concerning this protein was the discovery that phorbol esters were also a ligand for activating this protein; this created a direct link between PKC and the formation of various tumors.

THIAZOVIVIN: THE PLURIPOTENCY INDUCER

4987 | Mar 20 2012

POTENTIAL OF EMBRYONIC STEM CELLS OF HUMAN (hESCs): The stem cells are not only known for their property of pluripotency in nature which means they have the potency to replicate in an indefinite manner but also famous for their capability of getting differentiate into all other kinds of cells and organelles from the three basic germinal layers named as ectoderm, mesoderm and endoderm. Embryonic stem cells of human (hESCs) have the ability of producing various numbers of types of cells in contrast to adult stem cells having the capability of producing only a limited cell types. Due to their pluripotency hESCs or human embryonic stem cells are of great interest and importance for the scientists and researchers as they are being used for detection and analysis of different genetic disorders of human in their research. The successful models of Human Embryonic Stem Cells are made for Fragile-X syndrome and Cystic fibrosis (CF) etc like genetic maladies and their will be many more in upcoming years. In olden years the usual practice was to use embryo to generate pluripotent stem cells which is brought down very significantly due to the process of insertion of various genes like Sox2, Oct4 and Klf4 etc into differentiated cells. These genes can enhance the pluripotency in differentiated cells and make them exactly like embryonic stem cells. A recent more advanced approach is to use molecules like Thiazovivin.

FINGOLIMOD – THE IMMUNOMODULATOR

4795 | Mar 19 2012

Introduction: Fingolimod and Multiple Sclerosis One of the most widely used fungi in Chinese herbal medication is the ascomycete “Isaria sinclairii”. Known for its medical properties for centauries it was examined more closely after the immunosuppressant cyclosporin was discovered from a fungal source. From a screening of the extracts from this fungus came the molecule myriocin which demonstrated immunosuppressant properties as hope, however, it also killed the host in animal models. This molecule proved to be far too toxic for clinical use hence the molecule skeleton was used as a template to derive a series of derivatives in the effort to reduce the toxicity but preserve the immunosuppression potency. From this process came FTY720 which was researched pre-clinically in the area of transplant rejection, before being released in clinical trials as Fingolimod . [Read the Full Post]

Introduction: Multiple Sclerosis Multiple sclerosis is probably a condition that everybody has heard off but not many really understand the cause or nature of this destructive disease. Basically this disease is what is known as an inflammatory disease which affects area of the lining in the spinal cord or brain stem. The effect of this is the slow degradation of the functions of the spinal cord and brain stem. This means a loss of motor control, loss of communicative functions, loss of sight and digestive difficulties. Accompanying these debilitating symptoms are almost constant pain and fatigue, life quality of most suffers becomes very poor. There is currently no known cure for this disease, while treatment focuses on alleviating the symptoms or retarding the progression of the disease but always the end point is the same. Patients with this disease are known to try any form of treatment scientifically proven or not in the hope a remission can be triggered. Remission is the peculiar aspect of this disease in that it appears in phases with periods of relative peace in-between. However, relapses are usually progressively worse accumulating damage to essential functions that cannot be repaired. [Read the Full Post]

DASATINIB – THE DOUBLE-EDGED SWORD

5476 | Mar 13 2012

Introduction: BCR-ABL and SCR targets Researchers are continuously searching for the magic compound which will cure all diseases but most know that this is a physical impossibility. Every disease is different and especially cancers where even tumors of the same site / type can be radically different. In CML, AML and ALL a mutation in two chromosomes has been linked to the onset of these diseases in a proportion of patients. The defect is referred to as the “Philadelphia chromosome”, here a section of chromosome 9 and chromosome 22 have swapped places (translocated). The end result is that chromosome 9 is longer than it should be while chromosome 22 is shorter than it should be. The significance of this change is that the coding for the BCR gene and the ABL gene become mixed up (fused). The protein from this genetic fusion is referred to as the BCR-ABL fusion protein. Studies have shown that this protein is related to the protein kinase super family and has serine / threonine kinase activity, it also has phosphorylation activity for the cytoskeletal enzyme p21 Rac (Cdc42). Imatinib is a small molecule inhibitor of the ABL in Chronic Myeloid Leukemia, Acute Myeloid Leukemia and Acute Lymphoblast Leukemia tumors that has been proven very successful in the clinic. However, patients with the translocated gene demonstrate resistance to Imatinib due in part to the nature of fused BCR-ABL gene. [Read the Full Post]

Enzastaurin, as the inhibitor of PKC, may be a novel PNC medical therapy

5032 | Sep 29 2011

Pancreatic cancer is the fourth most common cause of cancer death both in the United States. Regarding the pathology, pancreatic cancer mainly includes exocrine pancreas cancers, pancreatic cystic neoplasms and endocrine pancreatic cancers. Pancreatic neuroendocrine cancers (PNC) account for less than 3% of pancreatic tumors and the main treatments are surgery, hormone therapy, chemotherapy and so on at this stage. However, It is still needed to search for effective treatments for PNC, and understand the molecular pathways regulating neuroendocrine tumor cell proliferation. [Read the Full Post]
