An unprecedented N-chlorinative ring contraction of 1,2-diazines was discovered and investigated with an electrophilic chlorinating reagent, trichloroisocyanuric acid (TCICA). Through optimization and mechanistic anal., the assisting role of n-Bu4NCl as an exogenous nucleophile was identified and the optimized reaction conditions were applied to a range of 1,4-dimethoxyphthalazine derivatives Also, an improvement of overall efficiency was demonstrated by the use of a labile O-silyl group. A bicyclization/ring-opening mechanism inspired by the Favorskii rearrangement was proposed and supported by the DFT calculations Furthermore, the efforts on scope expansion as well as the evaluation of other electrophilic promoters revealed that the newly developed ring contraction reactivity was a unique characteristic of 1,4-dimethoxyphthalazine scaffold and TCICA.

A review. The pharmacol. profile of the class of 1-anilino-(4-pyridylmethyl)-phthalazines is presented. 1-Anilino-(4-pyridylmethyl)phthalazines are potent, selective and orally well absorbed inhibitors of vascular endothelial growth factor (VEGF) receptor tyrosine kinases. In vitro they block VEGF-stimulated autophosphorylation of KDR expressing cells, resulting in the inhibition of survival effects of VEGF on endothelial cells. They also block platelet derived factor-mediated effects at slightly higher concentration but do not affect other pathways such as the bFGF receptor.

Weiss, Matthew M. published the artcileSulfonamides as Selective NaV1.7 Inhibitors: Optimizing Potency and Pharmacokinetics While Mitigating Metabolic Liabilities, Name: 6-Bromo-1,4-dichlorophthalazine, the publication is Journal of Medicinal Chemistry (2017), 60(14), 5969-5989, database is CAplus and MEDLINE.

Several reports have recently emerged regarding the identification of heteroarylsulfonamides as NaV1.7 inhibitors that demonstrate high levels of selectivity over other NaV isoforms. The optimization of a series of internal NaV1.7 leads that address a number of metabolic liabilities including bioactivation, PXR activation, as well as CYP3A4 induction and inhibition led to the identification of potent and selective inhibitors that demonstrated favorable pharmacokinetic profiles and were devoid of the aforementioned liabilities. The key to achieving this within a series prone to transporter-mediated clearance was the identification of a small range of optimal cLogD values and the discovery of subtle PXR SAR that was not lipophilicity dependent. This enabled the identification of compound 20, which was advanced into a target engagement pharmacodynamic model where it exhibited robust reversal of histamine-induced scratching bouts in mice.

An eco-friendly and efficient green protocol is developed for the synthesis of sixteen pyrazolo-phthalazine derivatives (5a-p) by using inexpensive biodegradable eggshell powder (ESP) as a heterogeneous catalyst. The four-component one-pot condensation reaction proceeded through Knoevenagel-Michael reaction of different chosen active methylene compounds, phthalic anhydride, and hydrazine hydride with various substituted aromatic aldehydes in the water at 60 degrees C, and furnished the high yields of products (93-98%) in rapid reaction time of 28 to 45 min. The material was characterized by different analytical techniques (SEM, TEM, XRD, BET, and FT-IR), and was composed of the high percentage of calcium oxides and carbonates, and less percentage of Na and Mg elements (based on EDX analysis). The ESP material displayed recyclability (4 times) without any notable loss of catalytic efficacy. Besides, this procedure offers 98% of the atom economy and 100% of carbon efficiency together with significant fiscal and enviro-friendly benefits.

1. Aldehyde oxidase (AO) is a liver cytosolic molybdoflavoprotein enzyme whose importance in drug metabolism is gaining in the recent. The objective of this work is to find a potent and selective inhibitor for AO activity using phthalazine oxidation as a marker reaction. 2. Among organic solvents tested, it was identified that methanol was not a suitable choice for AO activity even at concentrations less than 0.2% v/v. Acetonitrile and DMSO did not show any effect till 0.5% v/v but thereafter activites tend to decrease. 3. For selectivity, 23 compounds were selected and evaluated for their effects on AO and nine CYP450 enzymes. Among the tested compounds chlorpromazine, estradiol, hydralazine, quetiapine and raloxifene were selected based on their potency of inhibition towards AO activity. 4. Raloxifene was found to be a non-specific inhibitor of all major tested CYP450 enzymes and was excluded as a selective inhibitor for AO. Quetiapine also showed a degree of inhibition towards the major CYP450 tested. Hydralazine used as a specific inhibitor during the past for AO activity demonstrated a stimulation of AO activity at high and low concentrations respectively and the inhibition noted to be time dependent while inhibiting other enzymes like monoamine oxidase. 5. Estradiol showed no inhibition towards the tested CYP450 enzymes and thus proved to be a selective and specific inhibitor for AO activity with an uncompetitive mode of inhibition.

1-Azidophthalazine 9A is generated in trace amount by mild FVT of tetrazolo[5,1-a]phthalazine 9T and is observable by its absorption at 2121 cm(-1) in the Ar matrix IR spectrum. Ar matrix photolysis of 9T/9A at 254 nm causes ring opening to generate two conformers of (o-cyanophenyl)diazomethane 11 (2079 and 2075 cm(-1)), followed by (o-cyanophenyl)carbene (3)12, cyanocycloheptatetraene 13, and finally cyano(phenyl)carbene (3)14 as evaluated by IR spectroscopy. The two carbenes (3)12 and (3)14 were observed by ESR spectroscopy (D vertical bar hc = 0.5078, E vertical bar hc = 0.0236 and D vertical bar hc = 0.6488, E vertical bar hc = 0.0195 cm(-1), respectively). The rearrangement of 12 reversible arrow 13 reversible arrow 14 constitutes a carbene carbene-rearrangement. 1-Phthalazinylnitrene (3)10 is observed by means of its UV-vis spectrum in Ar matrix following FVT of 9 above 550 degrees C. Rearrangement to cyanophenylcarbenes also takes place on FVT of 9 as evidenced by observation of the products of ring contraction, viz., fulvenallenes and ethynylcyclopentadienes 16-18. Thus the overall rearrangement 10 -> 11 -> 12 reversible arrow 13 reversible arrow 14 can be formulated.
