Nanoscale liposomal formulation of a SYK P-site inhibitor against B-precursor leukemia

We report preclinical proof of principle for effective treatment of B-precursor acute lymphoblastic leukemia (ALL) by targeting the spleen tyrosine kinase (SYK)-dependent antiapoptotic blast cell survival machinery with a unique nanoscale pharmaceutical composition. This nanoscale liposomal formulation (NLF) contains the pentapeptide mimic 1,4-Bis (9-O dihydroquinidinyl) phthalazine/hydroquinidine 1,4-phathalazinediyl diether (C61) as the first and only selective inhibitor of the substrate binding P-site of SYK. The C61 NLF exhibited a very favorable pharmacokinetic and safety profile in mice, induced apoptosis in primary B-precursor ALL blast cells taken directly from patients as well as in vivo clonogenic ALL xenograft cells, destroyed the in vivo clonogenic fraction of ALL blast cells, and, at nontoxic dose levels, exhibited potent in vivo antileukemic activity against patient-derived ALL cells in xenograft models of aggressive B-precursor ALL. Our findings establish SYK as an attractive molecular target for therapy of B-precursor ALL. Further development of the C61 NLF may provide the foundation for therapeutic innovation against therapy-refractory B-precursor ALL.

Crystallographic Study on the Structure of 5,6,7,8-Tetrahydro-1,4-di (2 ‘-pyridyl) Phthalazine

The solid-state structure of 5,6,7,8-tetrahydro-1,4-di(2’-pyridyl)phthalazine (6-dppn) was characterized by X-ray diffraction and a crystallographic study was then conducted. It was found that 6-dppn exists in the trans/trans conformation. This ligand crystallizes in P2(1)/c(14) space group with unit cell parameters of a = 9.698(2) angstrom, b = 9.999(4) angstrom, c = 10.7268(3) angstrom, beta = 92.890(6)degrees, Z = 8 and V = 2958.2(14) angstrom(3). The non-covalent interactions involved in the structure of 6-dppn were investigated and presented in terms of supramolecular chemistry and crystal engineering.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 83-38-5. Name: 2,6-Dichlorobenzaldehyde.

Imidazole-containing phthalazine derivatives inhibit Fe-SOD performance in Leishmania species and are active in vitro against visceral and mucosal leishmaniasis

The in vitro leishmanicidal activity of a series of imidazole-containing phthalazine derivatives 1-4 was tested on Leishmania infantum, Leishmania braziliensis and Leishmania donovani parasites, and their cytotoxicity on J774.2 macrophage cells was also measured. All compounds tested showed selectivity indexes higher than that of the reference drug glucantime for the three Leishmania species, and the less bulky monoalkylamino substituted derivatives 2 and 4 were clearly more effective than their bisalkylamino substituted counterparts 1 and 3. Both infection rate measures and ultrastructural alterations studies confirmed that 2 and 4 were highly leishmanicidal and induced extensive parasite cell damage. Modifications to the excretion products of parasites treated with 2 and 4 were also consistent with substantial cytoplasmic alterations. On the other hand, the most active compounds 2 and 4 were potent inhibitors of iron superoxide dismutase enzyme (Fe-SOD) in the three species considered, whereas their impact on human CuZn-SOD was low. Molecular modelling suggests that 2 and 4 could deactivate Fe-SOD due to a sterically favoured enhanced ability to interact with the H-bonding net that supports the antioxidant features of the enzyme.

Effects of 6-(4-chlorophenoxy)-tetrazolo[5,1-a]phthalazine on Anticoagulation in Mice and the Inhibition of Experimental Thrombosis in Rats

Thrombosis is a major complication that could be fatal in acute or chronic cardio-cerebral-vascular diseases. Therefore, the development of novel agents for anticlotting and the prevention of thrombosis and cardiovascular diseases are clinically significant. This study aimed to evaluate the anticoagulant and antithrombotic effects of 6-(4-chlorophenoxy)-tetrazolo[5,1-a]phthalazine (Q808), a new phthalazine tetrazole derivative. Bleeding time, clotting time, and serum calcium ion (Ca2+) concentration were assessed in mice, whereas arteriovenous thrombus weight and plasma prothrombin time were evaluated in rats, and platelets Ca2+ influx was determined in rabbit. Daily oral administration of Q808 at 25, 50, or 100 mg/kg for 3 days significantly delayed bleeding time and clotting time in mice compared with controls. Q808 administration at 50 mg/kg significantly reduced experimental thrombus weight by 62.6% and delayed plasma prothrombin time by 58.7% in rats, whereas 50 and 100 mg/kg of Q808 daily significantly increased serum Ca2+ concentration in mice. Q808 at 0.2, 0.4, and 0.8 mg/mL significantly inhibited thrombin-induced Ca2+ influx in rabbit platelets. Our results suggest that Q808 at 25-200 mg/kg daily exerts anticoagulant and antithrombotic effects, and its mechanisms of action may involve both the intrinsic and extrinsic coagulation pathways that inhibit certain coagulation factors and platelet functions.
