The structure-activity relationship of a series of orally active glycoprotein IIb/IIIa antagonists containing a nitrogen heterocycle grafted onto a 3,4-dihydro-1(1H)-isoquinolinone core is described. These compounds are structurally novel analogs of the progenitor compound 1 (L-734,217, [[3(R)-[2-(piperidin-4-yl)ethyl]-2-oxopiperidinyl]acetyl]-3(R)-methy-beta- alanine) in which the lactam chiral center has been removed. The 4- piperazinyl- and 4-piperidinyl-substituted 3,4-dihydro-1(1H)-isoquinolinones were found to be optimal for in vitro potency. In addition, substitution at the 3-position of the beta-amino acid enhanced potency with the 3-pyridyl and 3-ethynyl analogs being the most potent prepared. Attempts to improve the in vivo profile of these compounds focused on modification of the physical properties. Ester prodrugs were prepared to increase the lipophilicity and remove the zwitterionic nature of the antagonists. The prodrug approach, coupled with the arylpiperazine terminus (pK(a) = ~9.0), afforded moderately basic and relatively nonpolar compounds. The acid N-[[7-(piperazin-1-yl)- 3,4-dihydre-1(1H)-oxoisoquinolin-2-yl]acetyl]-3(S)-ethynyl-beta-alanine, 6d (L- 767,679), is a potent fibrinogen receptor antagonist able to inhibit the ADP- induced aggregation of human gel-filtered platelets with an IC50 of 12 nM. Although 6d is orally active based on the results of an ex vivo dog assay at 0.3 mg/kg, the ethyl ester prodrug of this compound, 19 (L-767,685), is better absorbed at this dose than 6d. Upon oral dosing, the ester 19 is converted to 6d in vivo in dog with an estimated oral systemic availability of >17% (0-8 h, AUC(19po)/AUC(6div)). In addition, studies in monkey at an oral dose of 1 mg/kg show that 19 affects the complete inhibition of the ex vivo platelet aggregation in response to ADP between 2 and 8 h postdose with the level of inhibition remaining at 40% at 12 h postdose. This level of activity was superior to that observed for 6d and 1 at the same dose. Using ex vivo ADP-induced aggregation data from rhesus monkey (n = 2, 0-8 h using the AUC(19po)/AUC(6div)), the estimated systemic oral availability of 6d when dosed as 19 is 32%.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 42923-79-5, help many people in the next few years.Computed Properties of C9H10N2O2

(Chemical Equation Presented) Computer modelling suggests that 7-benzylamino-1-isoquinolinamines should mediate antimalarial effects by a mechanism distinct from that employed by existing antimalarial drugs. A series of these compounds was prepared in seven synthetic steps, via reductive amination of 1,7-isoquinolinediamine. In vitro efficacy testing of the novel compounds against Plasmodium falciparum revealed them to be potent antimalarial agents.
