Abstract: The present invention relates to dual-targeting cytotoxic compounds of formula (I) and to their preparation. The described compounds are endowed with tumour specific action, incorporating three functional units: a tumour recognition moiety and a tumour selective enzymatic substrate sequence connected together by means of a spacer. These conjugates are designed to guarantee serum stability and, at the same time, the desired action inside the tumour cells as a result of enzymatic cleavability. [(L-D)nE]m-F-D-PI-SI-CT Formula (I).

Abstract: Compounds of Formula (I) are described in which the R1 group is as defined in the specification and includes the condensation of the camptothecin molecule in position 7 with a cyclopeptide containing the RGD sequence. Said compounds are endowed both with high affinity for integrin receptors ?v?3 and ?v?5 and with selective cytotoxic activity on human tumour cell lines at micromolar concentrations.

Abstract: Compounds of Formula (I) are described: in which the R1 group is as defined in the specification and includes the condensation of 7-t-butoxyiminomethylcamptothecin in position 20 with a cyclopeptide containing the RGD sequence. Said compounds are endowed both with high affinity for integrin receptors ?v?3 and ?v?5 and with selective cytotoxic activity on human tumour cell lines at micromolar concentrations.

Abstract: Formula (I) compounds are described c(R1-Arg-Gly-Asp-R2) where the meanings of the various groups are as described here below, which are integrin inhibitors, and particularly inhibitors of integrins of the ?,?3 and ?,?5 family, and therefore are useful as medicaments, particularly for the treatment of the diseases underlying abnormal angiogenesis, such as retinopathy, acute renal failure, osteoporosis and metastases. The compounds described herein, when suitably labelled, are also useful as diagnostic agents, especially for the detection of small tumour masses and arterial occlusion events, and as targeted drug vectors.

Abstract: Compounds of formula (I) cyclo [NX1-R1-CO—NX2-R2-CO—NX3-R3-CO—NX4-CO—NX5-R5-CO], wherein at least one x-fluoroalkylated amino acid is present, are inhibitors of integrins, particularly those belonging to the alphavbeta3 and alphavbeta5 family, and thus are useful as medicaments, particularly for the treatment of the underlying diseases responsible for abnormal angiogenesis, such as retinopathy, acute kidney failure, osteoporosis and metastases. The compounds described herein are also useful as diagnostic agents, when appropriately labelled, especially for the detection and location of small tumour masses and arterial occlusion events.

Abstract: Salts of glycosaminoglycans (heparin, its fractions or fragments which are supersulfated, dermatan sulfate, heparan sulfate, and modified heparins) with bases of formula (I), ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, and R.sub.4 represent H, alkyl, or cycloalkyl; R.sub.5 and R.sub.6 represent H, or alkyl; R.sub.7 and R.sub.8 represent H or alkyl; n and m are integers from 1-4 and X is --O--CO--O--, which salts have the pharmacological properties of the glycosaminoglycans themselves, and are orally and rectally administrable.
