Aleuritic acid (AL) was protected at 9, 10 position by dimethoxy propane. The protected AL (Pro.AL) was further polymerized to obtain linear protected polyaleuritic acid (PAL) by dehydropolycondensation. Effects of various kinetic and thermodynamic parameters were studied. After polymerization, the deprotection of PAL was carried out. The synthesized PAL and PAA were characterized by using various techniques such as FT-IR, LC-MS, SEC, NMR (1H and 13C), 13C CP/MAS (Cross Polarization / Magic Angle Spinning) of solid PAA, DSC, SEM and TEM etc. The micelle and inverted micelle -structure in polar and nonpolar solvents are highlighted</p>1 aPandey, Asutosh, K.1 aNande, Smita, S.1 aSelukar, Balaji, S.1 aGarnaik, Baijayantimala  uhttps://library.ncl.res.in/content/synthesis-and-characterization-novel-value-added-biodegradable-polyaleuritic-acid-renewable00630nas a2200157   4500008004100000245010000041210006900141260000800210300001400218490000600232100002400238700002200262700002300284700002800307856013700335       2012                        eng d00aSynthesis of linear polylactic acid –based urethanes using tin modified closite -30b catalyst0 aSynthesis of linear polylactic acid based urethanes using tin mo  cJAN  a161 - 1710 v31 aSelukar, Balaji, S.1 aParwe, Sharad, P.1 aMohite, Kavita, K.1 aGarnaik, Baijayantimala  uhttps://library.ncl.res.in/content/synthesis-linear-polylactic-acid-%E2%80%93based-urethanes-using-tin-modified-closite-30b-catalyst02722nas a2200301   4500008004100000022001400041245012500055210006900180260008400249300001400333490000600347520162800353653002701981653004202008653001102050653001702061653002002078653000802098653002402106653001902130100002202149700002502171700002302196700002402219700002102243700002802264856012802292       2014                        eng d  a1178-201300aSynthesis of ciprofloxacin-conjugated poly(L-lactic acid) polymer for nanofiber fabrication and antibacterial evaluation0 aSynthesis of ciprofloxacinconjugated polyLlactic acid polymer fo  aPO BOX 300-008, ALBANY, AUCKLAND 0752, NEW ZEALANDbDOVE MEDICAL PRESS LTDcMAR  a1463-14770 v93 a<p>Ciprofloxacin was conjugated with polylactide (PLA) via the secondary amine group of the piperazine ring using PLA and 7-(4-(2-Chloroacetyl) piperazin-1-yl)-1-cyclopropyl-6-fluoro-1, 4-dihydro-4-oxoquinoline-3-carboxylic acid. Zinc prolinate, a biocompatible catalyst was synthesized, characterized, and used in ring opening polymerization of L-lactide. Five different kinds of OH-terminated poly(L-lactide) (two-, three-, four-, six-arm, star-shaped) homopolymers were synthesized by ring opening polymerization of L-lactide in the presence of dodecanol, glycerol, pentaerythritol, dipentaerythritol as initiator and zinc prolinate as a catalyst. The structures of the polymers and conjugates were thoroughly characterized by means of gel permeation chromatography, matrix-assisted laser desorption/ionization-time of flight mass spectrometry, and nuclear magnetic resonance spectroscopy. PLA (molecular weight = 100,000) and ciprofloxacin conjugated PLA were used for fabrication of nonwoven nanofiber mat (diameter ranges; 150-400 nm) having pore size (62-102 nm) using electrospinning. The microbiological assessment shows that the release of ciprofloxacin possesses antimicrobial activity. The drug-release behavior of the mat was studied to reveal potential application as a drug delivery system. The result shows that the ciprofloxacin release rates of the PLA conjugate nonwoven nanofiber mat could be controlled by the drug loading content and the release medium. The development of a biodegradable ciprofloxacin system, based on nonwoven nanofiber mat, should be of great interest in drug delivery systems.</p>10aantibacterial activity10aciprofloxacin conjugated polylactides10aCP-PLA10adrug release10aelectrospinning10aMDR10anonwoven nanofibers10azinc prolinate1 aParwe, Sharad, P.1 aChaudhari, Priti, N.1 aMohite, Kavita, K.1 aSelukar, Balaji, S.1 aNande, Smita, S.1 aGarnaik, Baijayantimala  uhttps://library.ncl.res.in/content/synthesis-ciprofloxacin-conjugated-polyl-lactic-acid-polymer-nanofiber-fabrication-and-0
