Abstract

Pyrazolone based metal complexes have strong bio-activity but the anti-cancer mechanism of these derivatives is not fully understood. In recent years, Cu(II) complexes have attracted the interest of researchers increasingly because of their high antitumor activities that are usually related to DNA binding. The reaction of three different derivatives (I) PPMP [3-methyl-1-phenyl-4-propionyl-1H-pyrazol-5(4H)-one], (II) TMCPMP [1-(3-chlorophenyl)-3-methyl-4-(4-methylbenzoyl)-1H-pyrazol-5(4H)-one] and (III) PPTPMP [3-methyl-4-propionyl-1-p-tolyl-1H-pyrazol-5(4H)-one] of 3-methyl-1-phenyl-1H-pyrazol-5(4H)-one and 2.2' bipyridyl along with Cu(NO3)2·3H2O under methanolic condition allowed us to isolate and characterize a series of new mixed ligand complexes [Cu(TMCPMP) (Bipy)NCS] (1) [Cu(PPMP) (Bipy)NCS] (2) and [Cu(PPTPMP) (Bipy)NCS] (3). All complexes are well characterized by elemental analysis, metal estimation, molar conductivity, FT-IR and UV-Vis spectroscopy. The molecular geometry of these complexes has been determined by single crystal X-ray study. The single-crystal X-ray structures of complexes 1 and 2 exhibit square pyramidal geometry, while complex 3 revealed slightly distorted square-pyramidal geometry. The DNA binding of...Continue Reading

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.

Antifungals

An antifungal, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis, cryptococcal meningitis, and others. Discover the latest research on antifungals here.

Cancer Metabolism: Therapeutic Targets

Targeting the mechanisms by which cancer cells acquire energy for metabolic needs is a therapeutic target. Discover the latest research on cancer metabolism and therapeutic targets.

Cancer Metabolism

In order for cancer cells to maintain rapid, uncontrolled cell proliferation, they must acquire a source of energy. Cancer cells acquire metabolic energy from their surrounding environment and utilize the host cell nutrients to do so. Here is the latest research on cancer metabolism.

Antivirals (ASM)

Antivirals are medications that are used specifically for treating viral infections. Discover the latest research on antivirals here.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
