The existence of three distinct classes of endocytic vesicles that are part of the pathway of fluid-phase endocytosis has been demonstrated by flow cytometry. Amounts of fluorescent and scattered light were measured on a particle-by-particle basis for unfractionated whole cell lysates from cells incubated with fluorescein isothiocyanate-dextran. After 20 min two different fluorescent population...

In the title compound, C13H13NO3, the isoxazole ring is approximately coplanar with the phenyl ring, the dihedral angle between their planes being 7.37 (19)°. In the crystal, centrosymmetrically related mol-ecules are linked into dimers by pairs of C-H⋯O hydrogen bonds, generating a ring of graph-set motif R 2 (2)(10).

In the title compound, C(22)H(30)NO(2)P, the P atom has an irregular tetra-hedral geometry. In the crystal, mol-ecules are connected by N-H⋯O hydrogen-bonding inter-actions, giving rise to a chain along the b axis. The phenyl ring of the anilino group is twisted by 77.40 (16)° relative to the other phenyl ring. The absolute configuration of phospho-rus is S(p).
