Abstract

SINTESA 1,2-BIS(FOSFINO) ETANA UNTUK PREPARASI TETROFOSMIN DAN SENYAWA TURUNANNYA. Senyawa 1,2-bis (fosfino)etana adalah senyawa khelat bidentat sederhana dengan atom fosfor sebagai donor ligan. Telah dilakukan sintesa 1.2bis(fosfino)etana melalui dua tahap: reaksi trietil fosfit dengan 1,2 dibromo etana didapat senyawa tetra etil etilen difosfonat (fosforan), reduksi fosforan dengan LiAlH4 diperoleh senyawa fosfin 1.2- bis(fosfino)etana. Analisa hasil dari setiap tahap reaksi dilakukan dengan mengamati spektrum infra merah, spektrum massa serta kromatografi cairan dan telah diperoleh hasil senyawa fosfin 1,2 bis-(fosfino) etana sebagai starting material dalam sintesa tetrofosmin dan senyawa turunannya dengan kemurnian lebih 98 % dan rendemen sebesar 34%. Kata kunci: 1,2-bis (fosfino)etana, khelat bidentat, sintesa SYNTHESIS OF 1.2-BIS(PHOSPHINO)ETHANE FOR PREPARATION OF TETROFOSMINE AND DEREVATIVES. 1.2-bis(phosphino)ethane is a simple chelate bidentate based on phosphorous as a donor ligands . The 1.2-bis(phosphino)ethane was synthesized through two steps reaction: triethyl phosphite was coupled with dibromo ethane to give tetra ethyl ethylene diphosphonate (phosphorane), the reduction of phosphorane by LiAlH4 gave the phosphine compound 1.2-bis(fosfino)etana. Investigation of the product every steps reaction by observing infra red spectra, as well as mass spectrometric and high performance liquid chromatographic analysis showed that the product was pure phosphine 1,2 bis-(phosphino) ethane as starting material in the synthesis of tetrofosmine and derivatives, the purity more than 98% and yield was around 34 %. Key words: 1.2-bis(phosphino)ethane, chelate bidentate, synthesis.

Abstract

ABSTRAKUJI BIODISTRIBUSI DAN UJI PREKLINIS MIKROSFER GELAS-P-32 UNTUK PENGOBATAN KANKER.Radiofarmaka telah  menunjukkan  manfaat lebih unggul dan spesiflk biladibandingkan dengan teknik pelayanan kesehatan lain, terutama untuk keperIuan diagnosis dan terapi beberapa penyakit  mematikan seperti kanker. Mikrosfer gelas-P-32 ( P-32 GMS ) adalah  salah  satu sediaan  baru  radiofarmaka untuk terapi  dengan cara  radiasi  interna beberapa penyakit  kanker ganas  seperti  penyakit  kanker  hati. Mikrosfer  gelas-P-32 ini  disiapkan  dengan  cara  mengira diasikan mikrosfer gelas-P31dengan neutron di reaktor nuklir, kemudian sediaan disuntikkan ke daerah yang terkena kanker Untukmemudahkan  penyuntikan  pada  sediaan  ini  perlu ditambahkan larutan pensuspensi, yaitu campuran dari PVP 16 %, dekstrose 50% dan salin. Mengingat ukuran mikrosfer ini spesiflk yaitu 40-60 J.Ull  maka pemilihan jamm suntik perIu dilakukan agar P-32 GMS yang diinjeksikan maksirnal bisa masuk ke daerah sasaran, dan mikrosfer tidak mengalami kerusakan karena gesekan dengan permukaan dalam  jarum. Ujibiodistribusi perIu dilakukan untuk melihat apakah P-32 GMS yang telah diinjeksikan terak1.lmulasike daerah penyuntikan  atau  terdistribusi  ke organ - organ lain yang  tidak dikehendaki, Hewan percobaan yang dipakai  adalah  mencit dengan penyuntikan dilakukan  pada otot  paha  kanan. Hasil biodistribusi pada I, 3dan  24 jam  setelah  injeksi  menunjukkan 100% aktivitas P-32 GMS terakumulasi di daerah penyuntikan.Hasil biodistribusi pada 5 jam setelah penyuntikan menunjukkan adanya penimbunan  aktivitas di organ lambung selain penimbunan aktivitas di daerah penyuntikan, namun hal ini diduga karena terjadi kontaminasi akibat kesalahan kerja .Kata Kunci : Radiofarmaka, , Mikrosfer gelas, P-32,  iradiasi, uji biodistribusi , kanker. ABSTRACTBIODISTRIBUTION AND PRECLINICAL TEST OF P-32 GLASS MICROSPHERESFOR CANCER THERAPY. The superiority of  radiophannaceutical compare to the  other  techniques off medical services, especially for diagnosis and  therapy  of  several deadly diseases such as cancer, shows that this technique is more specific and accurate. P-32-Glass microsphere (P-32 GMS) is one of theradiophannaceuticals developed reccntly for therapy using  interrnal  radiation  method  for several malignant cancers, such as hepatic canccr. 111cP-32 GMS was prcpared by irradiating P-31 GMS with neutron at a nuclear reactor, then the preparation was injected to the cancerous infected  area. To make easy  injection, it needs suspension agent that was including PVP, dextrose and saline with a composition of 16% PVP - 50%dextrose - saline as 2 : 3 : 3 (v/v/v). As microsphere size should be maintained at 40-60 11m, the injectionneedle was selected properly in order to remain the particle size of P-32 GMS unchanged  when  the frictionoccurs between microspheres and the inside surfaces of the needle. The injection  needle  used  was needle produced  by BD with a typical size of 20 GI Tw. Biodistribution  studies were carried out after I, 3, 5 and24 hour of injection. Experimental results  for 1, 3 and 24 hour post -injection studies showed  that 100%activity of  P-32 GMS was accumulated  at  the  injected  area. For 5 hour post-injection study, accumulation of  P-32 GMS activity was also found at stomach besides the injected area, but it was presured as working error. Keywords: Radiophannaceutical , glass microspheres ,P-32,  biodistribution, , cancer.
