`known in the art. See, e.g., U.S. Pat. No. 5,202,309 and
`International PCT Application WO 00/08197. In another pre(cid:173)
`ferred embodiment, the lipopeptide is a daptomycin-related
`molecule, including, inter alia, daptomycin, A54145, a dap(cid:173)
`tomycin-related lipopeptide disclosed in U.S. Pat. Nos. 5
`4,537,717, 4,482,487, Re. 32,311, Re. 32,310, U.S. Pat. No.
`5,912,226, currently in reissue as U.S. Ser. No. 09/547,357,
`U.S. Provisional Applications Nos. 60/170,943, 60/170,946
`or 60/170,945, filed Dec. 15, 1999, U.S. Provisional Appli(cid:173)
`cation No. 60/208,222, filed May 30, 2000, all of which are 10
`specifically incorporated herein by reference, or anA-21978
`antibiotic in which the n-decanoyl fatty acid side chain of
`daptomycin is replaced by an n-octanoyl, n-nonanoyl, n-un(cid:173)
`decanoyl, n-dodecanoyl, n-tridecanoyl or n-tetradecanoyl 15
`fatty acid side chain. The daptomycin-related lipopeptides
`disclosed in 60/170,943, 60/170,946, 60/170,945, and
`60/208,222 relate to synthetic and semisynthetic lipopeptides
`in which the ornithine or kynurine residues or the fatty acid
`side chain of daptomycin are modified. In a more preferred 20
`embodiment, the lipopeptide is daptomycin. The term dapto(cid:173)
`mycin-related lipopeptide refers to compounds described
`above, and salts thereof.
`The term "daptomycin" refers to the n-decanoyl derivative
`of the factor A-21978C0 type antibiotic, or a pharmaceutical 25
`acceptable salt thereof. "Daptomycin" is synonymous with
`LY146032. See FIG. 1.
`The term "anhydro-daptomycin" refers to the daptomycin
`derivative in which the a-aspartyl group of daptomycin is
`transpeptidated to an anhydro-succinimido group. See FIG.
`3.
`
`The term "~-isomer" or "~-isomer of daptomycin" refers
`to the daptomycin derivative that contains a ~-aspartyl group
`instead of an a-aspartyl group. See FIG. 2.
`Daptomycin or a daptomycin-related lipopeptide is "sub(cid:173)
`stantially pure" when at least 95% of a sample is daptomycin
`or daptomycin-related lipopeptide. Preferably, daptomycin
`or daptomycin-related lipopeptide is "substantially pure"
`when at least 97% of a sample is daptomycin or daptomycin(cid:173)
`related lipopeptide.
`Daptomycin or daptomycin-related lipopeptide is "essen(cid:173)
`tially pure" when at least 98% of a sample is daptomycin or
`daptomycin-related lipopeptide. Preferably, daptomycin or
`daptomycin-related lipopeptide is "essentially pure" when at
`least 99% of a sample is daptomycin or daptomycin-related 45
`lipopeptide.
`Daptomycin or daptomycin-related lipopeptide is "sub(cid:173)
`stantially free" of another compound when the other com(cid:173)
`pound is present in an amount that is no more than 1% of the
`amount of the daptomycin or daptomycin-related lipopeptide 50
`preparation.
`Daptomycin or daptomycin-related lipopeptide is "essen(cid:173)
`tially free" of another compound when the other compound is
`present in an amount that is no more than 0.5% of the amount
`of the daptomycin or daptomycin-related lipopeptide prepa- 55
`ration.
`Daptomycin or daptomycin-related lipopeptide is "free" of
`another compound when the other compound is present in an
`amount that is no more than 0.1% of the amount of the
`daptomycin or daptomycin-related lipopeptide preparation.
`Alternatively, daptomycin or daptomycin-related lipopeptide
`is "free" of another compound when the compound caunot be
`detected by HPLC under conditions of maximum sensitivity
`in which a limit of detection is approximately 0.05% or less of
`the amount of the daptomycin or daptomycin-related lipopep(cid:173)
`tide preparation. Exemplary HPLC methods are described
`herein (Tables 1 and 2).

`"Purified" daptomycin or daptomycin-related lipopeptide
`refers to substantially pure daptomycin or daptomycin-re(cid:173)
`lated lipopeptide, essentially pure daptomycin or daptomy(cid:173)
`cin-related lipopeptide, or a salt thereof, or to daptomycin,
`daptomycin-related lipopeptide, or a salt thereof which is
`substantially free, essentially free, or free of another com-
`pound.
`"Partially purified" daptomycin or daptomycin-related
`lipopeptide
`refers
`to daptomycin, daptomycin-related
`lipopeptide, or a salt thereof that is less than 90% pure.
`The purity of daptomycin, daptomycin-related lipopeptide
`or of another lipopeptide refers to the lipopeptide prior to its
`formulation in a pharmaceutical composition. The purity may
`be measured by any means including nuclear magnetic reso(cid:173)
`nance (NMR), gas chromatography/mass spectroscopy (GC/
`MS), liquid chromatography/mass spectroscopy (LC/MS) or
`microbiological assays. A preferred means for measuring the
`purity of daptomycin is by analytical high pressure liquid
`chromatography (HPLC).
`The term "micelle" refers to aggregates of amphipathic
`molecules. In an aqueous media, the lipophilic domains of the
`molecules of the aggregate are oriented toward the interior of
`the micelle and the hydrophilic domains are in contact with
`the medium. Micelle structures include, but are not limited to,
`spherical, laminar, cylindrical, ellipsoidal, vesicular (liposo(cid:173)
`mal), lamellar and liquid crystal. See FIG. 14.
`The term "mixed micelle" refers to a particular type of
`micelle in which the micelle contains more than a single type
`of amphipathic molecule. In the context of this invention,
`30 mixed micelles contain a lipopeptide and at least one other
`amphipathic molecule which may be another lipopeptide.
`Mixed micelles contain at least 10% of the lipopeptide by
`weight. In other embodiments, a mixed micelle contains at
`least 20%, 30%, 40%, 50%, 60%, 70%, 80% or 90% of the
`35 lipopeptide.
`The term "micellar solution" refers to a solution in which
`more than 50% of the lipopeptide molecules in the solution
`are present in micelles, as measured by weight. Preferably, at
`least 60%, 70%, 80%, 90% or 95% of the molecules are
`40 present in micelles. A micellar solution is retained on a ultra(cid:173)
`filtration membrane that has a 1 0, 000 dalton nominal molecu(cid:173)
`lar weight (NMW) cutoff.
`The term "critical micelle concentration" (erne) refers to
`the particular concentration of molecules, which is dependent
`upon temperature, salt concentration and the nature and type
`of amphipathic molecule. Above the erne, the unassociated
`monomers and micelles exist in equilibrium.
`The term "monomer" refers to an amphipathic molecule
`that is not part of an aggregate but that exists as a single
`molecule. In the context of this invention, the term monomer
`refers to a non-associated lipopeptide.
`The term "monomeric solution" refers to a solution in
`which more than 50% of the lipopeptide molecules are
`present as monomers as measured by weight. Preferably at
`least 60%, 70%, 80%, 90% or 95% are present as monomers.
`A monomeric solution is not retained on a ultrafiltration
`membrane that has a 10,000 dalton NMW cutoff but rather
`passes through the membrane.
`The term "low ionic strength buffer" refers to a solution
`60 that has a salt concentration below 50 mM; the term "medium
`ionic strength buffer" refers to a solution that has a salt con(cid:173)
`centration between 50-250 mM; the term "high ionic strength
`buffer" refers to a solution that has a salt concentration greater
`than250mM.
