Description
Vynález sa týka piperazínových derivátov majúcich predĺženú uroselektívnu αρ -adrenoceptorovú antagonistickú aktivitu prevyšujúcu aktivitu vyššie opísaných zlúčenín. Zlúčeniny podľa vynálezu sú sľubné pre liečbu benígnej prostatickej hyperplázie (BPH). Vynález sa tiež týka spôsobov prípravy týchto zlúčenín, farmaceutických kompozícií obsahujúcich tieto zlúčeniny a spôsobov liečby benígnej prostatickej hyperplázie pomocou týchto zlúčenín.The invention relates to piperazine derivatives having an extended uroselective α-α-adrenoceptor antagonist activity in excess of that of the compounds described above. The compounds of the invention are promising for the treatment of benign prostatic hyperplasia (BPH). The invention also relates to methods for the preparation of these compounds, pharmaceutical compositions comprising the compounds, and methods for the treatment of benign prostatic hyperplasia with these compounds.
Doterajší stav technikyBACKGROUND OF THE INVENTION
Review v J.Med.Chem., 1997, roč.40, č. 9, str. 1292-1315, opisuje najdôležitejšie súčasné farmakologické možnosti liečby benígnej prostatickej hyperplázie. Dve najúspešnejšie terapie sú založené na antagonizme k α-adrenergným receptorom a modulácii hladiny androgénov pomocou inhibítorov 5a-reduktázy. Inhibítory 5a-reduktázy majú obmedzenú účinnosť čo sa týka doby okamžitej symptomatickej a urodynamickej úľavy, αι-antagonisti sa javia ako omnoho účinnejšie, poskytujú okamžité subjektívne symptomatické zlepšenie a sú teda výhodným variantom liečby pri kontrole benígnej prostatickej hypertrofie, aiadrenoceptory sú prítomné tiež v krvných cievach a hrajú významnú úlohu pri regulácii krvného tlaku.Review in J. Med. Chem., 1997, 40, no. 9, p. 1292-1315, describes the most important current pharmacological options for the treatment of benign prostatic hyperplasia. The two most successful therapies are based on antagonism to α-adrenergic receptors and modulation of androgen levels by 5α-reductase inhibitors. 5α-reductase inhibitors have limited efficacy in terms of immediate symptomatic and urodynamic relief, α 1 -antagonists appear to be more effective, provide immediate subjective symptomatic improvement and are therefore a preferred treatment option for the control of benign prostatic hypertrophy, and the adrenoceptors are also present in blood vessels and play an important role in regulating blood pressure.
Antagonisti αι-adrenoceptorov sú teda látky obzvlášť dôležité, aj keď boli pôvodne vyvinuté ako antihypertenzné činidlá a majú tiež pravdepodobne prospešné účinky pri dysfunkcii metabolizmu lipidov a rezistencii k inzulínu, ktoré sú obvykle so základnou hypertenziou asociované.Thus, α-adrenoceptor antagonists are particularly important, although they were originally developed as antihypertensive agents and are also likely to have beneficial effects in lipid metabolism dysfunction and insulin resistance, which are usually associated with underlying hypertension.
Dôležitejší antagonisti αι-adrenoceptorov, ktorí sa v súčasnosti používajú pri kontrole BPH, sú:More important α-adrenoceptor antagonists currently used in BPH control are:
PRAZOSIHPRAZOSIH
TERAZOSINterazosin
OABOUT
(R)-(-)-TAMSUI-OSIM(R) - (-) - Tamsui-OSIM
Väčšina z týchto známych látok má však vedľajšie účinky na cievy (napríklad posturálnu hypertenziu, mdloby, závraty, bolesť hlavy, atd’.), čo je zapríčinené neselektivitou účinku na prostatické a vaskuláme αι-adrenoceptory. Je teda zrejmé, že antagonisti aj-adrenoceptorov, ktorí vykazujú väčšiu selektivitu pre prostatické αι-adrenoceptory, ponúkajú potenciál väčšieho urodynamického zlepšenia. To teda podtrhuje dôležitosť nájdenia pre prostatu selektívnych antagonistov aj-adrenoceptorov, ktoré poskytnú urodynamícké zlepšenie bez vedľajších účinkov spojených so súčasnými liekmi.However, most of these known substances have vascular side effects (e.g. postural hypertension, fainting, dizziness, headache, etc.), which is due to the non-selectivity of the effect on the prostate and vascular α-adrenoceptors. Thus, it is clear that α-adrenoceptor antagonists, which show greater selectivity for prostate α-adrenoceptors, offer the potential for greater urodynamic improvement. This underlines the importance of finding selective α-adrenoceptor antagonists for the prostate that will provide urodynamic improvement without the side effects associated with current drugs.
Nedávno sa ukázalo, že prostatické tkanivo vyšších živočíchov ako je človek, alebo pes, je obsadené cti a subtypom nízko afinitných adrenoceptorov. To dáva možnosť vyvinúť látky so selektívnym účinkom pri týchto patologických urodynamických stavoch. Vynález je zameraný na vývoj nových α i-antagonistov, osobitne novej triedy piperazínových zlúčenín s ·· ···· väčšou selektivitou účinku na αι-adrenoceptory, a ktoré by teda ponúkali úľavu od prostatickej hypertrofie rovnako ako základnú hypertenziu.It has recently been shown that prostate tissue of higher animals, such as man or dog, is occupied by the honor and subtype of low affinity adrenoceptors. This gives the possibility to develop substances with selective effect in these pathological urodynamic conditions. The invention is directed to the development of novel α 1 -antagonists, in particular a new class of piperazine compounds with greater selectivity of action on α-adrenoceptors, and which would therefore offer relief from prostatic hypertrophy as well as underlying hypertension.
V literatúre môžeme nájsť mnoho opisov farmakologických aktivít fenylpiperazínov. Eur. J. Med. Chem.-Chimica Therapeutica, 1977, roč. 12. č. 2, str. 173 až 176, opisuje substituované trifluórmetylfenylpiperaziny majúce cyklo-imidoalkylové postranné reťazce, pozri obr. nižšie, ako anorektické látky bez nežiadúcich vplyvov na CNS.Many descriptions of the pharmacological activities of phenylpiperazines can be found in the literature. Eur. J. Med. Chem.-Chimica Therapeutica, 1977, vol. 12. č. 2, p. 173-176, discloses substituted trifluoromethylphenylpiperazines having cyclo-imidoalkyl side chains, see Figs. lower than anorectic agents without adverse effects on the CNS.
Bola opísaná tiež syntéza a farmakológia niektorých 2-[3-(4-aryl-l-piperazinyl)propyl]lH-benz[de]izochinolín-l,3-(2H)-diónov/2,5-pyrolidíndiónov (J. Indián. Chem. Soc., 1986, V. LXIII, str. 529 až 530), N-(N4-aryl-N1-piperozinylmetyl)-4-(4'-metoxyfenyl)piperidín-2,6diónov (J. Indián Chem Soc., 1978, roč. LV, str. 819 až 821) a N-(N4-arylpiperazinylalkyl)ftalimidov (J Indián Chem Soc, 1979, roč. LVI, str. 1002 až 1005), uvedených nižšie. Tieto látky vykazovali antihypertenzívne a CNS tlmiace aktivity u experimentálnych zvierat.The synthesis and pharmacology of some 2- [3- (4-aryl-1-piperazinyl) propyl] -1H-benz [de] isoquinoline-1,3- (2H) -dione / 2,5-pyrrolidinediones has also been described (J. Indian) Soc., 1986, V. LXIII, pp. 529-530, N- (N 4 -aryl-N 1 -piperosinylmethyl) -4- (4'-methoxyphenyl) piperidine-2,6-dione (J. Indian) Chem Soc., 1978, Vol. LV, pp. 819-821) and N- (N 4 -arylpiperazinylalkyl) phthalimides (J Indian Chem Soc, 1979, Vol. LVI, pp. 1002-1005), listed below. These compounds exhibited antihypertensive and CNS depressant activities in experimental animals.
V týchto publikáciách však nie je žiadna zmienka o adrenoreceptorovej blokátorovej aktivite týchto zlúčenín a teda ich vhodnosť pre liečbu benígnej prostatickej hyperplázie z nich neplynie.However, there is no mention in these publications of the adrenoreceptor blocker activity of these compounds, and therefore their suitability for the treatment of benign prostatic hyperplasia does not arise from them.
Skoršie syntézy rôznych l-(4-aryl-piperazin-l-yl)-3-(2-oxo-pyrolidin-l-yl/piperidín-lyl)-alkánov a ich vhodnosť ako hypotenzívnych a antiischemických látok bola uvedená v nepublikovaných indických patentových prihláškach DEL 496/95 (3. brezna 1995), DEL/500/95 (21. marec 1995) a DEL/96/96 (29. marca 1996). Tieto zlúčeniny majú nízku ap adrenergnú blokátorovú aktivitu (pKi ~ 6 v porovnaní s aktivitou > 8 pri známych αρ antagonistoch, ako je prazozín) a prakticky nemajú selektivitu k a]A podskupine adrenoceptorov v porovnaní s cxib alebo ocid adrenoceptormi. Nedávno bolo zistené, že štrukturálna modifikácia týchto zlúčenín, zmena laktámu na dioxo zlúčeniny, to je 2oxopyrolidín na 2,5-dioxopyrolidín a 2,6-dioxopiperidín, zvyšujú adrenoceptorovú blokátorovú aktivitu a tiež veľmi zvyšujú selektivitu pre ajA oproti aiB-adrenoceptorovej blokátorovej aktivite, čo jasne ukazuje, že tieto zlúčeniny sú dobrými kandidátmi liekov BPH.Earlier syntheses of various 1- (4-aryl-piperazin-1-yl) -3- (2-oxo-pyrrolidin-1-yl / piperidin-lyl) -alkanes and their suitability as hypotensive and anti-ischemic agents have been reported in unpublished Indian patent applications. applications DEL 496/95 (3 March 1995), DEL / 500/95 (21 March 1995) and DEL / 96/96 (29 March 1996). These compounds have a low and p adrenergic blocking activity (pKi ~ 6 as compared to that of> 8 in the known αρ antagonists such as prazosin), and practically no selectivity ms] A subset adrenoceptors compared to CXIB or ocid adrenoceptors. Recently, it has been found that structural modification of these compounds, the conversion of lactam to dioxo compounds, i.e., 2-oxopyrrolidine to 2,5-dioxopyrrolidine and 2,6-dioxopiperidine, increase the adrenoceptor blocker activity and also greatly increase selectivity for both A and Aβ-adrenoceptor blocker activity. , which clearly shows that these compounds are good candidates for BPH.

Femorálne artérie samcov živých wistar krýs, cez noc udržiavaných na ľahkej diéte, sa kateterizovali pri znecitlivení pentobarbitónom (35 mg/kg). Femorálny katéter sa vyviedol v oblasti krku a pomocou neho sa sledoval krvný tlak. Zlúčeniny podľa vynálezu (v dávkach 0,1, 0,3 a 1 mg/kg) sa podali 24 hodín po operácii, a to orálnou cestou pomocou sondy do žalúdka krysám, ktoré boli cez noc priviazané. Krvný tlak a srdcový rytmus sa zaznamenávali pomocou prevodníka tlaku Statham a polygrafii Grass a výsledky sú uvedené v tabuľke 4.Femoral arteries of male live wistar rats, kept on a light diet overnight, were catheterized under anesthesia with pentobarbitone (35 mg / kg). The femoral catheter was dislocated in the neck area and blood pressure was monitored. The compounds of the invention (at doses of 0.1, 0.3 and 1 mg / kg) were administered 24 hours post-operatively by oral gavage to rats that were bound overnight. Blood pressure and heart rhythm were recorded using a Statham pressure transducer and Grass polygraphy and the results are shown in Table 4.

Spontánne hypertenzné krysy pri vedomíSpontaneous hypertensive conscious rats
V tejto štúdii sa použili spontánne hypertenzné krysy vážiace medzi 250 až 300 g. Krysy sa cez noc pripútali. Krvný tlak sa monitoroval na chvostovej artérii pomocou poloautomatického neinvazívného prístroja na meranie krvného tlaku. Zlúčeniny podľa vynálezu (v dávkach 1,3, 10 a 30 mg/kg) sa podávali orálne. Krvný tlak bol pred a 1,5, 4, 6 a 24 hodín po podaní zlúčenín. Výsledky sú uvedené v tabuľke 5.Spontaneous hypertensive rats weighing between 250 and 300 g were used in this study. The rats were strapped overnight. Blood pressure was monitored on the tail artery using a semi-automatic non-invasive blood pressure measuring device. The compounds of the invention (at doses of 1.3, 10 and 30 mg / kg) were administered orally. Blood pressure was before and 1.5, 4, 6 and 24 hours after compound administration. The results are shown in Table 5.

In vivo štúdie selektivityIn vivo selectivity studies
Samce psov zmiešanej rasy (12 až 20 kg) sa znecitliveli pentobarbitálom sodným (35 mg/kg, intravenózne) Priedušnica sa intubovala kvôli umelej pľúcnej ventilácii. Do femorálnej artérie a femorálnej žily sa zaviedli kanyly, aby bolo umožnené meranie krvného tlaku, respektíve podávanie roztokov zlúčenín. Krvný tlak sa zaznamenával pomocou prevodníka tlaku a polygrafii. Vykonal sa rez blízko stredu laterálne k penisu a tak sa odhalil močový mechúr. Moč sa odviedol pomocou kanyly zavedenej priamo do mechúra a potom sa viedol do močovej trubice a umiestnil vo vývode prostaty. Balónik sa nafúkol asi 2 cm3 vzduchu a overilo sa jeho umiestnenie. Intrauretrálny tlak sa zaznamenával na polygrafe pripojenom k prevodníku tlaku. Závislosť tlaku na zvyšujúcej sa dávke fenylefrínu (1 až 16 pg/kg, intravenózne) sa získala pre tlak prostatický a krvný pred podaním zlúčenín podľa vynálezu. Potom sa intravenózne podávali zlúčeniny 2, 9, a 13 (v dávkach 0,01, 0,03, 0,1 a 0,3 mg/kg), a to 10 minút pred meraním kriviek odpovedí na fenylefrín. Výsledky sa analyzovali a vypočítali sa hodnoty ρΚβ spôsobom opísaným v Kenny et al. (1996). Výsledky sú uvedené v tabuľke 6.Mixed race male dogs (12-20 kg) were anesthetized with sodium pentobarbital (35 mg / kg, intravenous). The trachea was intubated for artificial lung ventilation. Cannulas were inserted into the femoral artery and femoral vein to allow blood pressure or compound solutions to be administered, respectively. Blood pressure was recorded using a pressure transducer and polygraphy. An incision was made near the center laterally to the penis to expose the bladder. Urine was collected via a cannula inserted directly into the bladder and then passed into the urethra and placed in the prostate duct. The balloon was inflated with about 2 cm 3 of air and verified its location. Intraurethral pressure was recorded on a polygraph attached to a pressure transducer. The pressure dependence on the increasing dose of phenylephrine (1-16 pg / kg, intravenous) was obtained for prostatic and blood pressure prior to administration of the compounds of the invention. Compounds 2, 9, and 13 were then administered intravenously (at doses of 0.01, 0.03, 0.1 and 0.3 mg / kg) 10 minutes prior to the measurement of phenylephrine response curves. The results were analyzed and ρΚβ values calculated as described by Kenny et al. (1996). The results are shown in Table 6.
