Abstract

Ribosome Inactivating Proteins (RIPs) are compounds isolated from plants with ability to inhibit protein synthesis. The inhibition of protein synthesis is due to inactivation of ribosomal RNA through a site-specific  deadenylation  mediated  by  RNA  N-glycosidase. Reportedly, RIPs mainly possess wide range of bioactivity including antiviral  activity  against  plant  infections.  Other  activities  of  RIP were  as  abortifacien,  antivirus  and  anticancer.  This  study  was aimed  to  isolate  and  characterize  the  optimum  conditions  for inducing  the  expression  of  recombinant  RIPs  isolated  from  the leaves  of  Mirabilis  Jalapa  L.  We  have  been  successfully  isolated several  RIPs  and  engineered  these  proteins  to  be  expressed  in  E. coli. These recombinant proteins were obtained by screening cDNA library  originated  from  the  mRNA  of  Mirabilis  jalapa  L  leaves,  and inserted  into  pUC19  carrying  lacZ  gene.  The  presence  of recombinant  plasmid  was  tested  by  using  α-complementation assay. Many RIPs have been isolated from plants and these proteins express  enzymatic  activity  by  cutting  supercoiled  double  stranded DNA. One RIP namely rMJC15310 was obtained from this study and the  proteins  having  ~  8kb  in  size,  cut  the  supercoiled  DNA  into linear  form  at  the  concentration  as  low  as  5  µg.  The  ability  to  cut supercoiled  DNA  increased  on  inducing  its  expression  with  0.4% IPTG.Key words:   Ribosome  Inactivating  Proteins  (RIP),  IPTG,  Mirabilis  jalapa L., recombinant protein

Abstract

The total protein of Mirabilis jalapa L leaves had the ability to cleave supercoiled DNA and showed toxicity on HeLa and Raji cell-lines. The 30 kD protein (MJ-30) purified by cationic exchange chromatography possessed activites as RIP e.g DNA supercoiled cleavage and RNA N-glycosidase activity. The aim of this study was to prepare pure MJ-30 and to observe the stability of MJ-30 .MJ-30 of M.jalapa L leaves was purified using the combination of ammonium sulphate fractionation and cationic exchange chromatography with NaCl gradient elution. MJ-30 was subjected for its stability to assays against pH, temperature, and storage period.Stability assay showed that MJ-30 is stabil at pH 5-6, then the activity decreased as the pH increased. This protein was stable at 300 – 550C, and the activity decreased when the temperature increased. Storage at 40C, MJ-30 was stable until 12 days but the activity was decreasing. However, at 300C, MJ-30 was stable for 3 days only. Glycerol addition to the MJ-30 solution has made the activity stable for 18 days at 40C and 300C storage.Keyword : Protein MJ-30, Leaves of Mirabilis jalapa L, stability, pH, temperature, storage

Abstract

LR-2(4-phenyl-3,4-dihydro-indeno[2’,1’]pyramidine-2(1H)- thione;  Leni  Ritmaleni  2),  which  designed  and  assumed  to  have biologically  activity  as  anticancer,  has  been  successfully synthesized  by  using  the  Biginelli  reaction.  This  research  was aimed  to  investigate  the  effect  of  benzaldehyde  excess  in  the synthesis  of  LR-2  and  to  evaluate  the  cytotoxic  activity  of  LR-2against HeLa cancer cell lines. The synthesis was done by reacting benzaldehyde, 2-indanone and together  with thiourea at one time as  said  as  one  pot  reaction  synthetic  methodology  and  the reaction was acid catalysed. The mole equivalent of benzaldehyde was  in  excess  compare  to  others.  The  effect  of  benzaldehyde  in excess is the higher the mole of benzaldehyde, the lower the yield of  LR-2.  The  cytotoxicity  of  LR-2  was  done  by  using  MTT  method and the LC50 was 268.15 μM.Key words : LR-2, benzaldehyde, cytotoxic, HeLa
