Description

트리시클릭 진통제{Tricyclic Analgesics}Tricyclic Analgesics &lt; RTI ID = 0.0 &gt;

만성 통증은 개체 집단에서 빈번한 증상이지만, 그의 병리생리학은 잘 알려져있지 않다. 하나의 가능성은 침해수용 척추 감각 뉴론이 외상 이후 부적절한 활성을 나타낸다는 것이다. 실험동물과 인간에서 척추 감각 뉴론은 외상 후, 과도-흥분되고 자발적 임펄스를 생산한다. 마츠너와 데보어(Matzner and Devor, 1992)는 만성 통증과 관련된 과도-흥분은 상처 부위에서 Na 채널 밀도가 증가하는데 기인하는 것으로 제시하였다. 또한, 신경 손상 이후, Na 전류의 동력학과 전압-의존 특성의 변화는 비정상적인 임펄스 발생과 척추 감각 뉴론의 과도-흥분에 기여한다고 가설화 되어 있다. 후근절(DRG) 뉴론은 빠른 테트로도톡신-민감(TTX-S) 전류와 느린 TTX-저항(TTX-R) 전류를 포함하는 Na 전류를 복잡하게 혼합하여 갖는다. 래트 DRG 뉴론에서, 생체내에서 통각과민을 생산하는 PEG2, 아데노신 및 세로토닌의 세 가지 인자는 TTX-R 전류의 크기를 증가시키고, 그의 전도성/전압 관계를 고-극성 방향으로 이동시킨다(Gold et al., 1996 참조). 신경 손상 이후, TTX-R 전류는 DRG 뉴론에서 하향 조절되고, 동일 동물에서 TTX-S 전류는 상향 조절된다(Cummings and Waxman, 1997 참조). Na 채널 특이성 항체를 사용하여, 데보어 등의 문헌(Devor et al., 1993 참조)은 Na 채널이 신경절로부터 발생한 신경종에 축적됨을 증명하였다. 손상된 축색 팁(tip)에서 Na 채널의 축적은 비정상적인 채널 흥분과, 인간에서 말단 신경 손상을 종종 병발시키는, 고통과 감각이상을 설명할 수 있다.Chronic pain is a frequent symptom in an individual population, but his pathophysiology is not well known. One possibility is that the infiltrating spinal sensory neurons exhibit inadequate activity after trauma. In experimental animals and humans, vertebral sensory neurons produce post-traumatic, transient-exciting, spontaneous impulses. Matzner and Devor (1992) suggested that transient-excitation associated with chronic pain is due to increased Na channel density at the wound site. It is also hypothesized that changes in the dynamics and voltage-dependent characteristics of Na currents after nerve injury contribute to abnormal impulse generation and transient-excitation of spinal sensory neurons. (DRG) neurons have a complex mixture of Na currents, including fast tetrodotoxin-sensitive (TTX-S) currents and slow TTX-resistor (TTX-R) currents. In rat DRG neurons, three factors, PEG 2 , adenosine and serotonin, which produce hyperalgesia in vivo, increase the magnitude of the TTX-R current and shift its conductivity / voltage relationship in the high-polarity direction (Gold et al., 1996). After nerve injury, the TTX-R current is down-regulated in the DRG neurons and the TTX-S current in the same animal is up-regulated (see Cummings and Waxman, 1997). Using the Na channel specific antibody, Devor et al. (See Devor et al., 1993) demonstrated that the Na channel accumulates in neurons originating from the ganglion. Accumulation of the Na channel in the damaged axon tip can account for abnormal channel excitement and pain and sensory disturbances, often accompanied by terminal nerve damage in humans.

척추 감각 뉴론의 엑손의 손상은 Na 전류를 변화시켜 실질적으로 그의 흥분성을 변화시키는 것으로 보인다. 따라서, Na 채널의 선택적 차단제는 포유동물에서 만성 통증의 예방 또는 치료를 위해 사용될 수 있다. Na 채널 차단제는 삼차신경통, 당뇨병성 신경병증, 편두통 예방 및 암 통증을 포함하는 만성 통증 증후군에 효과적인 것으로 알려져 있다[맥콰이 등의 문헌(McQuay et al., 1995 British Medical Journal, 1995, 311, 1047-1052)및 그에 인용된 문헌].Damage to the exon of the vertebrate sensory neuron seems to alter its excitability substantially by changing the Na current. Thus, selective blockers of the Na channel can be used for the prevention or treatment of chronic pain in mammals. Na channel blockers are known to be effective in chronic pain syndromes including trigeminal neuralgia, diabetic neuropathy, migraine prevention and cancer pain [McQuay et al., 1995 British Medical Journal, 1995, 311, 1047 -1052) and the literature cited therein.

그러나, 급성 또는 만성 신경 손상에 의한 통증은 치료가 어렵고 통상적인 진통제에 종종 내성을 가진다. 이와 같은 화합물은 일부 국소적 마취제 및 항경련제, 예를 들면, 리도카인, 에티도카인, 벤조카인, 테트라카인, 릴루졸, 페니토인 및 가바펜틴을 포함한다. 그들의 대부분은, 비록 Na 채널을 조절하는 기능을 가질지라도, 부작용의 높은 위험때문에 임상 사용이 제한되어 있다. 리도카인은 예를 들면 심혈관허탈과 이의 결과로 심정지를 일으킬 수 있다. 벤조카인은 호흡 곤란, 피부 발진, 홍반 및 부종을 유발할 수 있다. 발작성 장애에 대한 페니토인의 사용은 과혈당증을 유발할 수 있다.However, pain due to acute or chronic nerve damage is difficult to treat and is often resistant to conventional analgesics. Such compounds include some topical anesthetics and anticonvulsants such as lidocaine, etidocaine, benzocaine, tetracaine, riluzole, phenytoin and gabapentin. Most of them have limited clinical use because of the high risk of side effects, even if they have the ability to regulate Na channels. Lidocaine can cause cardiac arrest and cardiac arrest as a result, for example. Benzocaine can cause dyspnea, skin rash, erythema and edema. The use of phenytoin for paroxysmal disorders can lead to hyperglycemia.

만성 통증과 같은 신경병성 통증에 대한 화학 요법이 효과가 없고, 이와 같은 진통이 전형적으로 암 및 심각한 물리적 상해 및 당뇨병성 신경병증과 같은 질환과 관련되기 때문에, 심한 부작용의 발생없이 임상적으로 이용할 수 있는 화합물을 계속 찾을 필요성이 있다.Since chemotherapy for neuropathic pain such as chronic pain is ineffective and such pain is typically associated with diseases such as cancer and severe physical injury and diabetic neuropathy, it can be used clinically without severe side effects There is a need to continue to search for compounds that are present.

The spiro ring contains a nitrogen atom (i.e., NR 5 ) which may be basic when R 5 is, for example, alkyl, alkenyl or cycloalkyl. Such basic compounds can be reacted with conventional inorganic and organic acids to readily form pharmaceutically acceptable salts. Typical acids used for the formation of pharmaceutically acceptable salts of the present invention include those derived from hydrochloric, sulfuric, sulfamic, phosphoric, citric, succinic, glutamic, maleic, lactic, tartaric, p- toluenesulfonic, benzoic, oxalic, . This salt is prepared by simply contacting the spiro base with a suitable acid and generally in a solvent such as methanol or diethyl ether. Salts are generally highly crystalline, readily precipitate and are obtained by filtration. They may be further purified if desired by recrystallization from conventional solvents such as methanol, ethyl acetate, acetone and tetrahydrofuran.

Preferably by first preparing a compound wherein R &lt; 5 &gt; is hydrogen, and then reacting the compound with an R &lt; 5 &gt; -alkylation or -acylation agent. This reaction is shown in Scheme 1 below.

상기 식에서,In this formula,

R1, R2, R3, R4및 A는 상기와 같고, "L"은 통상의 이탈기(예, 클로로 또는 브로모와 같은 할로이거나 트리메틸실릴과 같은 실릴 유도체임)이다.R 1 , R 2 , R 3 , R 4 and A are as defined above, and "L" is a common leaving group (eg, halo such as chloro or bromo or a silyl derivative such as trimethylsilyl).

상기 반응은 대략 등몰량의 스피로 아민을 알킬화제 또는 아실화제(즉, L-R5)와 일반적으로 테트라히드로푸란, 디메틸술폭시드 또는 N,N-디메틸포름아미드와 같은 비반응성 유기 용매 중에서 화합하여 수행한다. 트리에틸아민 또는 NaHCO3와 같은 염기를, 원한다면 산 스캐빈저로 작용시키기 위해 사용할 수 있다. 약 25 내지 약 60℃에서 실행되는 경우, 반응은 전형적으로 약 2 내지 20시간 후에 실질적으로 완전히 이루어진다. 생성물을 반응 용매를 제거하여 용이하게 단리되고 추가의 정제는 원한다면 염 형성, 결정화 및 크로마토그래피와 같은 일반적 방법으로 수행할 수 있다.The reaction is carried out by combining approximately equimolar amounts of spiroamine with an alkylating agent or acylating agent (i.e., LR 5 ), generally in a non-reactive organic solvent such as tetrahydrofuran, dimethylsulfoxide or N, N-dimethylformamide. Base such as triethylamine or NaHCO 3 can be used to act as an acid scavenger if desired. When carried out at about 25 to about 60 &lt; 0 &gt; C, the reaction is typically substantially complete after about 2 to 20 hours. The product is easily isolated by removing the reaction solvent, and further purification can be carried out by customary methods such as salt formation, crystallization and chromatography, if desired.

한 가지 방법에서, 유도된 디에틸아민의 N-보호 형태를 반응식 2에 따라 비시클릭 케톤과 반응시킨다.In one method, the N-protected form of the derived diethylamine is reacted with bicyclic ketone according to Scheme 2.

상기 반응식 2에서, P는 용이하게 제거되는 아민-보호기, 예를 들면 에톡시 카르보닐 또는 벤질기이다. 보호된 디에틸아민 유도체는 비시클릭 케톤과 NaH와 같은 강염기의 존재하에 용이하게 반응한다. 이 반응은 스피로 아민 유도체를 형성하여 통상적인 방법으로, 예를 들면 염산과 반응시켜 용이하게 보호기 제거한다.In Scheme 2 above, P is an amine-protecting group such as an ethoxycarbonyl or benzyl group that is easily removed. Protected diethylamine derivatives readily react in the presence of strong bases such as bicyclic ketones and NaH. This reaction forms a spiroamine derivative and easily removes the protecting group by reacting with, for example, hydrochloric acid in a conventional manner.

Such compounds can be readily converted into the corresponding alcohols (R 1 is H and R 2 is OH) by reaction with a reducing agent such as NaBH 4 in a solvent such as methanol or ethanol.

알콜은 촉매 수소화, 예를 들면 탄소 상의 10% 팔라듐 존재하에 수소 가스와 반응시켜 추가로 환원시킬 수 있다. 이들 반응은 반응식 3에 도시되어 있다.The alcohol can be further reduced by reaction with hydrogen gas in the presence of catalytic hydrogenation, for example, 10% palladium on carbon. These reactions are shown in Scheme 3.

본 발명의 화학식 I의 화합물은 다르게는 반응식 4에 나타낸 바와 같이 적절하게 치환된 피레리딘 유도체로부터 출발하여 제조할 수 있다.Compounds of formula (I) of the present invention may alternatively be prepared starting from appropriately substituted pyrrolidine derivatives as shown in scheme (4).

고리화 반응은 치환된 피페리딘을 오염화인과 사염화티타늄과 같은 강한 탈수제와 일반적으로 벤젠, 톨루엔, 크실렌 또는 클로로포름과 같은 비반응성 유기 용매 중에서 반응시켜 수행한다. 반응은 30 내지 60℃에서 수행하는 경우 일반적으로 2시간 내에 완결된다.The cyclization reaction is carried out by reacting the substituted piperidine with a strong dehydrating agent such as contaminating phosphorus and titanium tetrachloride, generally in a non-reactive organic solvent such as benzene, toluene, xylene or chloroform. The reaction is usually complete within 2 hours if carried out at 30 to 60 &lt; 0 &gt; C.

고리화 생성물은 R1과 R2가 함께 모두가 옥소인 화학식 I의 화합물이며, 상기 반응식 3에 기재된 바와 같이 상응하는 알콜 또는 알칸(R1과 R2가 함께 수소임)으로환원될 수 있다.The cyclization product may be reduced to the R 1 and R a bivalent compound of formula I wherein both oxo together, the corresponding alcohol or alkane (R 1 and R 2 can not together hydrogen), which, as described in Scheme 3.

상기 반응식에서 요구되는 치환된 피페리딘은 반응식 5에 나타난 바와 같이 용이하게 제조된다.The substituted piperidines required in the above reaction schemes are readily prepared as shown in Scheme 5.

반응식 5에서, 메틸 4-피페리딘 포르메이트는 아민-보호제(즉, P가 삽입됨)와 반응된다. 전형적인 아민-보호기는 tert-부톡시 카르보닐, 벤질 및 트리메틸실릴을 포함한다. 보호된 피페리딘 유도체는 이어서 페닐 알킬 할리드, 예를 들면 페닐에틸 브로마이드(여기서, A는 CH2임), 2-페닐프로필 요오다이드(여기서, A는 CH-CH3임) 또는 3-페닐프로필 요오다이드(여기서, A는 CH2CH2임)와, NaH 또는 리튬디이소프로필아미드(LDA)와 같은 강염기 존재하에, 일반적으로 테트라히드로푸란 또는 벤젠과 같은 비반응성 용매 중에서 반응한다. 약 -20℃에서 수행되는 반응은 일반적으로 약 2 내지 4시간 후 실질적으로 완전히 이루어진다. 알킬화된 피페리딘은 이어서 보호기 제거화(L-보호기 제거)되고 PCl5와 TiCl4과 반응하여 고리화될 수 있거나, 먼저 고리화될 수 있고 L-보호기가 이어서 제거될 수 있다.In Scheme 5, methyl 4-piperidine formate is reacted with an amine-protecting agent (i. E., P is inserted). Typical amine-protecting groups include tert-butoxycarbonyl, benzyl, and trimethylsilyl. The protected piperidine derivatives are then reacted with a phenylalkyl halide, such as phenylethyl bromide, where A is CH 2 , 2-phenylpropyl iodide, wherein A is CH-CH 3 , or 3- In the presence of a strong base such as phenyl propyl iodide (where A is CH 2 CH 2 ) and NaH or lithium diisopropylamide (LDA), generally in a non-reactive solvent such as tetrahydrofuran or benzene. The reaction carried out at about -20 &lt; 0 &gt; C generally takes place substantially completely after about 2 to 4 hours. The alkylated piperidine can then be cyclized by first removing the protecting group (L-protecting group removed) and reacting with PCl 5 and TiCl 4 , or it can first be cyclized and the L-protecting group can then be removed.

This caused chronic pain in the leg for at least a week from the fifth day. On the day of the test, during the morning, the onset of the pain response was confirmed by the Randall and Celito tests and the animals defined by the pain threshold ψ100 units were selected. In the afternoon, measurements were taken again prior to previous administration of the test compound solution by subcutaneous route. This administration was performed 30 minutes before the onset of pain. For each batch, the analgesic effect (%) was calculated from the mean of the pain thresholds measured before and after treatment compared to the control animals that were only receiving vehicle only.
