Patent number: 11944688Abstract: The invention relates to improvements in drug delivery and more particularly to the use of Cell Penetrating Agents (CPA's) or Cell Penetrating Peptides (CPP's) which have been stabilized by, for example: i) stapling two amino acids to form Stapled CPP's (StaP's) or ii) stitching three or more amino acids to form stitched CPP's (StiP's). These stabilized CPP's are conjugated to a drug or Biologically Active Compound (BAC) directly or via a Bi-Functional Linker (BFL) so that the BAC can be carried though a cell membrane by the CPP.

Patent number: 11466691Abstract: A fault control protects a pump-motor assembly from monitored faults. The pump-motor assembly includes an electrical motor mechanically coupled to a pump. The fault control determines a speed of the motor. If the speed is determined to be less than a minimum speed, the fault control generates a fault signal to affect the operation of the motor. The fault control can also determine if a phase of the power provided to the motor is missing based on vibrations sensed by a vibration transducer. The fault control can also determine temperature faults based on signals from two thermocouples, including determination of loss of inlet or discharge flow.Type: GrantFiled: February 4, 2019Date of Patent: October 11, 2022Assignee: Franklin Electric Co., Inc.Inventors: Kevin Michael Fox, Amjad Masood, Benjamin W.

More particularly there is provided a drug carrying cell penetrating molecule (DCCPM) comprising: a biologically active compound (BAC), and a cell penetrating agent (CPA), which BAC and CPA are linked directly or via a bi-functional linker (BFL). The CPA is a stabilized peptide (CPP) which has a conformation imposed upon it by stapling to form a stapled peptide (StaP) or stitching to form a stitched peptide (StiP). The StiP or StaP comprise a cross link or bridge between at least two amino acids of the peptide and the cross link or bridge provides a cyclisation between at least two amino acids which are not formed by an olefin metathesis.Type: ApplicationFiled: June 28, 2018Publication date: March 3, 2022Applicant: Sutura Therapeutics LtdInventors: Keith Foster, Adam James Reginald Gadd
